The article considers the issues of geotechnical substantiation and application constructive technological measures for construction underground space up to 4.4 m deep in closed courtyard Palace built 18th century conditions weak water-saturated soils historical center St. Petersburg. 18.4 x 29.4 was arranged close proximity enclosing structures civil buildings - 19th centuries. presents design...

In the design of suspended diaphragm wall existing soil-rock foundation pit, bottom needs to reserve rock shoulder provide embedding, and prestressed anchor should be used lock foot at same time. It is first time propose a new type supporting structure without anchor, makes full use inner struts middle plate underground form stable system, which lacks engineering experience theoretical verifica...

The present paper describes and provides an analytical solution to the problem of stress state a limited-thickness soil basis resting on incompressible base, under action two distributed loads different intensities near retaining wall excavation pit. It is proposed that method for identifying components statement within framework engineering in question improved, based trigonometric Ribiere–Fil...

The health and productivity of mining operations are negatively impacted by coal mine fires, making them dangerous. It happened everywhere, in both working abandoned mines. This study seeks to review provide technical analytics potential fires fire detection a Dual-Cab suppression system. Analysis was done on like spontaneous combustion, flammable gas explosions, cab vehicle fires. Additionally...

Based on the deep foundation pit project of Laoguancun station Wuhan rail transit line 16 and according to engineering characteristics construction conditions site surrounding environment, method combining field monitoring finite element numerical simulation is adopted analyze law stress deformation during excavation support construction; it includes horizontal displacement underground diaphrag...

In the past, rock slope stability analysis were performed either graphically or using a hand-held calculator, but nowadays there are variety of slope stability analysis which can be used according to the field condition and potential failure mode. In 2-D analysis, effect of convex and concave walls are neglected, however concave slopes are believed to be more stable than straight walls due to t...
