Via a long-term comprehensive instrumentation program, the performance of a 26 m deep
metro station excavation constructed by the top-down method in downtown Shanghai was …

Soil pressure is a critical factor to pipe jacking projects both during and after the jacking.
Current practices are based on modifications of one of Terzaghi arching model, eg Japan …

Abstract Spaces for backfills are often constrained and limited to a narrow width when
retaining walls must be built close to existing stable walls in urban areas or near rock faces …

Underground backfill plays an important role in the mining industry, and is one of the key
elements in the routine operation of many underground mines. Its main role is to improve …

This paper presents the results of an experimental investigation of the active arching effect in
soils using the Digital Image Correlation (DIC) technique. A trapdoor apparatus was filled …

Mining backfill is widely used in underground mines worldwide. The stresses in backfilled
stopes must be correctly evaluated because they influence the ground stability and the …

Determination of stress distribution, giving due consideration to arching mechanism within
minefill stopes, is of great importance because of its influence on the ground stability, ore …

An X-section cast-in-place concrete (XCC) piled raft is a new type of foundation that uses
piles with X-shaped cross-sections. Compared to a traditional circular cast-in-place concrete …

Estimation of stresses in backfilled stopes is a critical issue for backfill design in
underground mines. This task can be accomplished by numerical modeling. To date, most …

The earth pressure coefficient K, defined as the horizontal to vertical normal (effective)
stresses ratio (σ h/σ v), is a key parameter in analytical solutions for estimating the stresses …
