Sentence examples for overlying bedrock from inspiring English sources

Fig. 2 Schematic representation of the 1D site response analysis method for a site consisting of n horizontal layers soils overlying bedrock.

In the greater Dublin area, there are extensive glacial sediments overlying bedrock, consisting of widespread boulder clay or till of varying thicknesses (up to 40 m) and areas of thick alluvial material along the River Liffey (McConnell 1994; Farrell and Wall 1990).

In the area, water flowing fractures generated by mining come through the overlying bedrock, and even reach the surface in some areas, resulting in damage to overlying aquifers.

Hydraulic fracturing increases permeability at depth, however, it affects a much smaller thickness than that of the overlying bedrock and occurs over too short a timescale to affect natural vertical head gradients.

Our review of the literature indicates that HF affects a very limited portion of the entire thickness of the overlying bedrock and therefore, is unable to create direct hydraulic communication between black shales and shallow aquifers via induced fractures.

The regolith is defined as weathered in situ and transported material overlying unweathered bedrock.

Luminescence data of 12.3 ka and 11.0 ka were obtained for basal sand deposits overlying slope bedrock and the Pleistocene terraces of the Orkhon River.

This paper attempts to assess the influence of dynamic soil structure interaction (SSI) on the behavior of seismically isolated cable-stayed bridge supported on a rigidly capped vertical pile groups, which pass through moderately deep, layered soil overlying rigid bedrock.

The present study investigates the effects of soil structure interaction (SSI) on the response of base-isolated multistory buildings founded on an elastic soil layer overlying rigid bedrock and subjected to a harmonic ground motion.

Overlying the bedrock are deposits of glacial sand and gravel, clay, and some alluvial deposits.

The objective of this study is to assess the effects of soil structure interaction on the response of seismically isolated bridge piers founded on a shallow soil stratum overlying a rigid bedrock and to develop a method that considers soil structure interaction and can be easily applied to the preliminary design of bridges.
