Landslide surges pose a serious threat to the ecological environment and human life safety. Based on rock structure mechanics water sediment dynamics, considering additional resistance caused by interference of loose landslide particles flow structure, this paper deduces calculation formula loose-rock when entering water. It modifies velocity (ASCE) recommended American Society Civil Engineers....

We present a borehole failure model which is based on fracture mechanics and layer buckling theories and compare its prediction with experimental data. The model assumes that the main mechanism of borehole collapse takes place in the form of layers buckling near the borehole surface. The model introduces a combination of fracture mechanics parameters with dimension of length that scale the size...

The mechanical behavior of multicracks under compression has become a very important project in the field of fracture mechanics and rock mechanics. In this paper, experimental and numerical studies on the fracture property of three collinear cracks under compression were implemented. The specimens were a square concrete plate, and the cracks were made by a very thin film. The tests were conduct...

Mechanical parameters of rock mass are essential in engineering for stability analysis, supporting design, and safety construction. The inverse analysis has been commonly used to determine the mechanical mass. In this study, a novel approach was proposed through combing high dimensional model representation (HDMR), Excel solver, numerical model. HDMR employed approximate nonlinear function betw...
