... problem. The kinematical element method (KEM) within a rigorous theoretical framework is used to solve this problem using the modified false-position method. The critical noncircular-failure surface and the associated minimum factor of safety are located using the KEM. A rock slope with planar failure...

... in the tunnel has a major influence on the internal force and deformation of the tunnel structure. When the fire occurs in the lower space of the tunnel, the fire safety of the internal box culvert structure should be paid more attention. The key design considerations have been identified as the concrete deck...

... Abstract Long-term driving and monotonous internal environment increase the safety hazard of driving in ultralong tunnels. Therefore, methods to alleviate the driving fatigue caused by long-term driving are of great significance to promote the safety of ultralong tunnel driving. Firstly...

... to the engineering safety [2]. However, the case of weathered rock mass are often encountered in vicinity of these projects [3]. Many field investigations revealed that a variety of fault fracture zones (FFZs) could be embedded inside the rock mass due to complex geological activities [1,4,5,6], which may result...

... Abstract Once a water supply pipeline bursts, the seepage field of the surrounding soil mass will change, and the safety of the adjacent foundation pit will be affected. In this study, a foundation pit accident was taken as an engineering case. On the basis of fluid-solid coupling theory...

... for assessing the sliding of slopes cannot be applied because no particular sliding plane exists in toppling failures. To overcome this difficulty, the author proposes a back analysis method for determining the factor of safety for the toppling failures of slopes during/after their constructions by using...

... would be 150m . The study was conducted to optimum slope design with special reference to F1 fault without sacrificing the safety of the mine operation (CSIR-CIMFR Report, 2017). The top soil of about 10m thickness forms the top most lithology in the project area. Soil is underlain by main overburden...

The plastic zone radius and maximum displacement around the two D-shape tunnels are determined and new support system is proposed. In this project, the excavation and support system...

... Abstract: Slope engineering is complex huge open system. Its deformation evolution characters and safety are controlled by many factors that are random and fuzzy and have nonlinear relationship. Because we can't understand mechanism well up date, support vector machine is attractive...

... Abstract: The stability of slopes can be assessed by a factor of safety, which is usually determined by a limit equilibrium method. In order to evaluate the factor of safety, we need such strength parameters as cohesion and the internal friction angle. In the monitoring of slope stability...

... Abstract: Rock slope stability analysis has been a challenging problem for civil and mining engineers. There are several modes of failure in which a rock slope can fail; a plane failure is one of them. In recent past, a generalized expression has been presented for the factor of safety...

It also can calculate the stabilizing tension and its direction to reach a predetermined factor of safety. Output files could be very large. An example is presented for both the traditional method...

... of its relation with displacements and safety factor is calculated based on static condition. Therefore, when displacements occur in a slope, limit equilibrium methods are not suitable to evaluate the effect of such displacements on total stability of the slope [2]. An example of such analysis has been...
