软土流变性对深基坑周围地表沉降的影响分析
摘要:在实测资料和前人研究的基础上,分析了软土地区深基坑围护结构水平位移值和墙后地表沉降的变化规律。对围护结构水平位移进行二次曲线拟合,假设地表沉降曲线形态可用正态分布密度函数来描述,利用地层损失法计算各工况下墙后最大地表沉降,并与各工况下实测最大地表沉降比较,提出了软土流变性对地表沉降规律的滞后影响。
Abstract:The relation between horizontal value behind of the diaphgram wall and settlement of the ground behind the diaphgram wall analyzed, based on the field investigation and previous research. Fitting the horizontal displacement with secondary curve, supposing ground settlement curve could be described by normal distribution density function. The maximum ground settlement can be calculate using ground-loss method in every case. And then it is compared to the maximum value measured in the field. The delay effect of creep of the soft soil to the ground settlement is presented.
