Abstract Precast slab parameters are important factors affecting the mechanical performance and service life of precast-slab-fabricated recyclable roads. To clarify force mechanism roads provide a basis for selecting parameters, field test road fabricated using large-scale precast was conducted in this study. The horizontal vertical stresses on top bottom surfaces determined. stress-time histor...

Stress arching effect during the excavation of broken surrounding rock in underground engineering has an important influence on stability after excavation. To determine stress horizontally layered jointed mass, characteristics mass is analyzed this study by using a series numerical tests. The formation mechanism arch revealed through comparison voussoir beam structure and theoretical analysis m...

This paper mainly studies the behavior of axisymmetric radial interaction between soil and structure under stress. Considering possible factors in interaction, such as arching effect caused by finite curvature, a simplified model is established. The influence curvature change on stress field, strain displacement field stress-strain relationship analyzed. Finally, status various their changes ar...

In the current paper results of a well instrumented experimental procedure for studying the arching effect in loose and dense sand are presented. The apparatus comprises concentric circular trapdoors with different diameters that can yield downward while stresses and deformations are recorded simultaneously. As the trapdoor starts to yield, the whole soil mass deforms elastically. However, afte...

Predicting the inner displacements of deep vertical shafts during excavation process has been a difficult task considering geological, structural, and constructional influences. In fact, two-dimensional (2D) analytical solution based on retaining wall model remains insufficient for understanding actual behavior an excavation. This is because deformation becomes complicated due to unexpected arc...

Induced trench method is a well-known technique usually used to reduce the soil pressure applied on buried pipes. This involves use of lightweight compressible material above pipe increase positive arching, and thus, decrease pipe. However, little efforts have been given by previous studies check applicability using tire-derived aggregate (TDA) as light weight in induced method, where it not cl...
