Numerical simulation of the effect of soil physical and mechanical properties on the stability of hole wall of bored pile
The stability of hole wall is the key factor to restrict the quality of bored pile,and the influence of soil physical and mechanical properties on the stability of hole wall is very important.The influence of physical and mechanical properties of soil on the stability of hole wall is simulated by using numerical simulation software ANSYS,and the influence of elastic modulus,cohesion,internal friction angle and Poisson's ratio of soil on the stability of hole wall is studied.The research shows that the node displacement at the hole wall is the largest,and the farther away from the hole wall,the smaller the node displacement and the better the stability.The influence of soil elastic modulus,cohesion and internal friction angle on hole wall stability is obvious,but the influence of soil Poisson's ratio on hole wall stability is small.The larger the elastic modulus,cohesion and internal friction angle of soil,the better the stability of hole wall.The smaller the cohesion and internal friction angle is,the more obvious the improvement of the cohesion and internal friction angle is to the stability of the hole wall.
