Patent number: 11703498Abstract: Disclosed is a three-parameter strength reduction method for slope stability evaluation. The present disclosure reflects the difference in the attenuation and contribution of the cohesion, internal friction angle and tensile strength in the process of slope instability by reducing the three parameters by different reduction factors. Based on the sudden change of the characteristic point displacement of the slope as a criterion of slope instability, the present disclosure derives the fitting relationship between the characteristic point displacement and the cohesion reduction factor. The present disclosure assumes that the comprehensive safety factor satisfies a linear relationship with the cohesion reduction factor, the internal friction angle reduction factor and the tensile strength reduction factor and derives the relationship between the comprehensive safety factor and the cohesion reduction factor.Type: GrantFiled: February 12, 2021Date of Patent: July 18, 2023Assignee: Shaoxing UniversityInventors: Yunjin Hu, Zhen Zhong, Huicai Gao, Zhenbo Wu, Huan Yang

Publication number: 20210139361Abstract: A device and method for mud solidification based on electro-osmosis well points cooperating with well-points dewatering. The method includes the following steps: 1) preparation; 2) construction of well point pipe positioning frame beams; 3) assembly of a mobile trestle platform; 4) well point pipe arrangement; 5) well point/electro-osmosis dewatering; 6) filtrate treatment; 7) well point pipe dismantling; and 8) excavation and transportation of solidified drilling slag for utilization. According to the disclosure, well point pipes are adopted and used as an anode and a cathode of an electro-osmosis well, and on-site quick solidification of pile foundation mud is implemented through the electro-osmosis combined with light well-points dewatering; by the adoption of the well point pipe positioning frame beams, the problems that drilling slag in a sedimentation tank has a large water content and it is difficult to arrange and fix the well point pipes are well solved.Type: ApplicationFiled: November 12, 2020Publication date: May 13, 2021Applicants: Shaoxing University, Zhejiang University City CollegeInventors: Yunjin HU, Feng CHEN, Jiqing JIANG, Lianying ZHOU, Lu SHI
