| 摘 要： | 应用FLAC^3D数值计算程序，分析了工程降水对深基坑坑底回弹的影响．结果表明：工程降水可以明显减小坑内土体的回弹量，但不会改变坑底回弹变形的趋势面形状；并且，开挖面下的工程降水深度越大，坑底的回弹变形越小．

| Abstract: | The numerical caculated programe FLAC^3D is applied to analyse the influence of the soil resilience of deep pit excavation＇s bottom by dewatering. Results show that the dewatering engineering can reduce the soil resilience, but it is not effective to change the outline of the upheaval ,and the resilience is opposite to the depth of dewatering. |
