挖井基础刚度的主要影响因素分析

Analysis on Main Factors Affecting Stiffness of Digging Well Foundation

通过挖井基础纵横向刚度的计算,分析了挖井基础刚度的主要影响因素:基础形状、基础混凝土强度等级、基础的受力形式、基础埋置深度、基础尺寸、冲刷深度。结果表明,基础混凝土强度对基础刚度影响较小,基础形状、基础的受力形式、基础埋置深度、基础尺寸、冲刷深度对基础刚度影响均较大。

According to the calculation of longitudinal and horizontal stiffness of digging well foundation, the main factors affecting the stiffness, including shape of the foundation, strength grade of the foundation concrete, form of force on the foundation, burying depth of the foundation, dimension of the foundation, scouring depth, were analyzed. The results show that the effect of the concrete strength on the stiffness is small, while the effect of Shape, the force form, the burying depth, the dimension, and the scouring depth is large.
