摘要
文中利用有限元模拟方法,分析支护桩水平位移随着土体模量、重度以及内摩擦角的变化规律.结果表明,随着土体模量的增加,支护结构的水平位移不断减小;随着土体重度的增加,支护结构的水平位移不断增加;随着土体内摩擦角的增加,支护结构的水平位移不断减小.土体模量增加可减少支护结构的桩侧变形,故基坑开挖过程中,有必要对土体进行合理加固,但加固时还应考虑采用的材料对土体重度和内摩擦角的影响.
Abstract
In order to analyze the influence of the horizontal displacement of the deep foundation pit supporting pile,the change law of the soil modulus,heavy weight and internal friction Angle is analyzed by using the finite element simulation method.The results show that the horizon-tal displacement of the supporting structure decreases;the horizontal displacement of the supporting structure increases with the increase of the soil mass and the supporting structure increases in the soil.Based on the above analysis,the increase of soil modulus can effectively reduce the pile side deformation of the supporting structure,so it is necessary to take reasonable reinforcement measures for the soil during the excavation,but the materials used in the reinforcement should also consider the influence on the heavy soil and the internal friction Angle of the soil.
