The field performance of a geotechnical structures including its failure mechanism should be evaluated in detail before construction in order to minimize the possibility of potential failure. In this paper, the application of soil nailing system is documented in a detailed based on case study in the north of Tehran, Iran. The total excavation depth for a 15 storey residual building wall brought...

Analysis of advanced displacement in construction progress of tunnel excavation with weak surrounding rock is carried out by numerical method and comparison of model test result. In allusion to the problems of regional landslides and extruded large-deformation seriously impacting the stability of rock mass in construction process of large-section tunnel with weak surrounding rock, the elastic-p...

Abstract In order to systematically evaluate the damage degree in Jinping deep tunnels during excavation, an improved SPH algorithm with good Lagrangian characteristics is introduced. By modifying derivative of traditional kernel functions, brittle failure processes particles are realized. The ‘Fissure Searching Generating Method’ (FSGM) has also been used determine establishment joints and tun...

Abstract In order to understand the mechanical behavior of a stope and analyse stress conditions surrounding rocks after ventilation shaft excavation abutment stresses top coal mining layout. situ uniaxial monitoring tests were performed field pressure evolution. Furthermore, variation concentration factor was studied using Tongxin Mine 8309 face TongMei Group, China, as case study. A loading m...
