摘要
将土岩组合区基坑外侧地表沉降视为偏态分布模式,通过试算法对偏态分布公式中关键参数进行调整。并将调整曲线与现场实测沉降曲线进行拟合,找出线性相关系数较大的参数值。在确定出关键参数之后,即确定偏态曲线的解析式,可为类似基坑工程地表沉降预测提供参考。
Method of ground settlement estimation in soil-rock mixed area is established regarding the surface settlement curve as decentration distribution curve model,in this paper we revised the key parameters in decentration distribution formula .Then we fitted the theoretical curve with the measured curve,and we decide key parameters through the linear correlation coefficient .After choose the key parameters,the decentration distribution analytic formula is defined,which could support theoretical prediction for foundation pit in the Soil-rock erea.
