Measuring Ground Movement by Precise Survey
The three dimensional surface movements of the retrogressive landslides at Beaver Creek were monitored from May, 1978 to August, 1979 using precise surveying techniques. A comprehensive, parametric, least squares adjustment computer program was developed to assist in the determination of the limit …

Prediction and Assessment of Ground Movement and Building Damage Induced by Adjacent Excavation
… problem is exacerbated when externally induced ground movements are imposed, as in the case of adjacent excavations. The following laboratory experiments were designed to better understand the intricate relationship between the installation of retaining systems and the potential occurrence of …

A return to the ground: movement, land, and modes of existence in Nkambeni, South Africa
… the dissertation argues that land reveals movement – conceptual, spatial, and relational – as central to the shaping of reality in Nkambeni. These movements are traced through the flows of knowledge, soil, and water, foregrounding tensions between modernist and otherwise ways of being. Such …

Subsidence Damaged Homes Over Room and Pillar Mines in Illinois (Ground Movements, Damage Criteria)
… is established between residential damage and ground movements over Illinois room and pillar mines. Using this ground movement-damage criterion and knowing the expected level of ground displacement house damage can be estimated. Subsidence characteristics observed at the ground surface over …

The Response of Buildings to Excavation-Induced Ground Movements
… and together they are used to provide a background for developing guidelines for controlling building damage and to develop a procedure for estimating building damage due to excavation-induced ground movement. The procedure developed for estimating building damage can be implemented for …

Distributed Sensing for Monitoring Cast Iron Pipe Behaviour
… between pipe leakage and differential ground movements. Seasonal ground movements were monitored using total station and Light Detection and Ranging (LiDAR) surveying equipment. Ground movements of 23 to 30 mm were detected from a roadway repair required to fix a water main break, …

ANALYSIS AND DESIGN OF EXCAVATION SUPPORT SYSTEM IN SOFT CLAY
… such as large strut loads and excessive ground movements are often encountered. Therefore, a method was proposed for the design of excavation support system in soft clay. The method provides a suitable approach to treat the problem of net active forces acting on the sheetpile below the …

Application and Evaluation of Non-Destructive Testing Methods for Buried Pipes
… to help establish the relationship between ground movement and cast iron water pipe breaks was then undertaken. A total of fifteen segments of 150 mm cast iron water pipes were monitored using an acoustic-based pipe condition assessment technique to estimate the remaining wall thickness and …

Interactive design of braced excavations
… It is a major concern of the designer to limit ground movement around an excavation in order to prevent damage to adjacent structures, utilities and roads. Existing design methods can accurately predict ground and wall movement of a braced excavation, but the calculations become complex when …

Ecological and Anthropogenic Influences on a Sentinel Species' Gut Microbiome
… fragment size, the subsequent exigency of ground movement, and overlapping home ranges to determine whether there is variation in the gut microbiome of Argentine black and gold howler monkeys due to these factors.</p>

Aquifer Compaction at Different Depths: Observations from a Vertical GPS Array at the University of Houston Coastal Center, Texas
… study area. GPS data, precipitation data, and groundwater head measurements were collected at the UHCC for two years (02/2014-02/2016). Ground deformation at 10, 20, 30, and 0 feet below the land surface (bls) were measured from four GPS stations and compared to rainfall and groundwater depth. …

Finite element analysis of embankment on soft Indian River clay
… stabilized earth embankment (up to 45 feet above ground level) was founded on a 60 ft. deep layer of soft clay. Consolidation of the soft, normally consolidated clay was accelerated through installation of an array of prefabricated vertical drains. The performance was monitored during staged …

A study of building response and damage due to mining-induced ground movements
… have been developed to predict mining-induced ground movements. Some of these methods, such as the profile and influence functions, have been used successfully in a number of applications. Prediction methods, however, do not address the response of surface buildings and structures to …

Evidence of Non-Strike Induced Chemosensory Searching by Eastern Copperheads (Agkistrodon Contortrix) During Cicada Predation
… recording was assigned to a behavioral category (ground movement, climbing, post-feeding movement, pausing, periscoping, eating, and fighting) based on the predominant behavior occurring within that minute and ecological context of the recording. We found statistically significant differences …

Optimizing resilience : performance based assessment of retrofits for wood-frame housing in San Francisco
… building stock to be able to withstand frequent ground accelerations while maintaining life-safety standards. Most housing in the City of San Francisco is more than a century old and unable to comply with the increasingly stringent code requirements. Wood-frame multi-unit structures in the City …

Analysis of NATM and shield tunneling in soft ground
Demand for new underground transportation systems and utility networks has increased the use of tunneling in soft ground. Many of these tunnels have to be constructed in difficult soil conditions, with strict constraints on ground movement control. Technological advances, such as the pressurized …

Prediction and interpretation of ground movements due to tunneling in stiff clay and impacts on adjacent structures
… around the precast lining in order to limit ground movements and potential damage to overlying structures. This thesis analyzes monitoring data from the Crossrail project involving twin tunnels construction using Earth Pressure Balance (EPB) machines in London Clay. The research focuses on …

Methodology for updating numerical predictions of excavation performance
… is designed to handle diverse designs, ground conditions, and sources of information during construction to operate within existing construction project management procedures (based on trigger levels for individual field measurements). The framework comprises three key components: 1) …
