通过理正软件根据实际基坑情况对最优方案进行分析,研究该方案下的水平位移的影响.通过改变桩径,分析并计算得出了在规范要求以及安全可靠的前提下,能够更加经济的细部参数方案.然后对提出的最优方案进行有限元模拟,得出位移分析以及沉降分析,对其进行合理化的验证.结论:随着开挖深度的增加,桩体的沉降呈现出先增大后减少的变化趋势,而土体的沉降量表现为逐渐减少.桩体和土体的水平位移从顶部往下均匀分布,并依次减少,最大水平位移均发生在桩顶.%According to the analysis method by Lizheng software and actual pit control variables to analyze and calculate the optimal solution,the results of horizontal displacement of the scheme are obtained.By changing the diameter of the pile,we can analyze and calculate the detailed parameter scheme that can be more economical under the premise of safety requirements and specifications.Then,the optimal scheme is simulated by finite element method,and the displacement analysis and settlement analysis are carried out to verify the rationalization.Conclusion:with the increase of excavation depth,the settlement of pile increases at first and then decreases,while the settlement of soil decreases gradually.The horizontal displacement of the pile and soil is uniformly distributed from top to bottom,and then the maximum horizontal displacement occurs at the top of the pile.
