چکیده
There is often obvious particle breakage for silica sand under high-stress, which will lead to the bearing capacity reduction and excessive settlement of foundation. This paper focuses on characteristics marine from East China Sea high-stress conditions. A series conventional triaxial tests sand, including consolidated drained (CD) undrained (CU) shear tests, were conducted confining pressures in range 2–8 MPa investigate rule during shearing process. The developments index Br with axial strain ε1 volumetric εv present hyperbolic linear trends, respectively. model was adopted describe relationship corresponding parameters obtained. also has a good correlation input work per unit volume various average stresses, regardless stress history. Furthermore, between fractal dimension studied based size distribution curve. It concluded that increases an up–convex trend increase index. dividing radius whether particles exhibit features determined as approximately 0.4 mm. anticipated provide reference supplementary test data analyzing constitutive models/environments regarding crushing.

An innovative type called "butterfly-shaped links steel plate shear wall (BLSPSW)" was proposed as a lateral load resisting system. In this novel system, by creating butterfly-shaped links in the four sides of the web plate, the lateral load resisting mechanism is not the development of a diagonal tension field on the web plate (similar to Conventional SPSWs), but the capacity of the system is ...

Fluid injection has been applied in many fields, such as hazardous waste deep well injection, forced circulation in geothermal fields, hydraulic fracturing, and CO2 geological storage. However, current research mainly focuses on geological data statistics and the dominating effects of pore pressure. There are only a few laboratory-conditioned studies on the role of drilling boreholes and the ef...
