摘要
根据沉降计算理论,引入二元联立方程组法、简易二元联立方程组法、均布桩二元联立方程组法计算刚性桩复合地基沉降,最后将工程实测结果和本文计算分析的结果进行对比分析,发现二元联立方程组法、简易二元联立方程组法与工程实测较为接近实测结果,均布桩二元联立方程组法与工程实测有一定偏差;为了更好的满足实际工程应用,对二元联立方程组、简易二元联立方程组进行修正,使其与工程实测值更为接近,更适合计算刚性桩复合地基的沉降。
According to the settlement calculation theory,dual-variable simultaneous equation set method,simple dual-variable simultaneous equation set method and dual-variable simultaneous equation set method of uniform piles were introduced to calculate the rigid pile composite foundation settlement,finally the actual engineering measurement result was compared and analyzed with the calculation analysis result,and it was found out that,the calculation results using dual-variable simultaneous equation set method and simple dual-variable simultaneous equation set method are close to the actual measurement results,whereas there is a certain deviation between dual-variable simultaneous equation set method of uniform piles and actual measurement result.In order to better meet the practical engineering application,the dual-variable simultaneous equation set method and the simple dual-variable simultaneous equation set method were revised to be more close to the engineering measurement value and more suitable for calculating the rigid pile composite foundation settlement.
