基坑降水对周围环境影响的研究

基坑降水分为维护结构插入不透水层的降基坑内水、插入不透水层的降坑内承压水和坑外降水3种情况.现有的基坑降水对周围环境影响预测方法可分为解析法、随机统计模型、人工智能模型和数值计算法及其他方法.基坑降水的数值模拟分析中多使用基于各种简化和假设的准三维模型,无法反映工程实际中地下水运动和土体变形的三维耦合关系;考虑三维水土耦合作用的真三维完全耦合数值模拟方法预测基坑降水对周边环境的影响将是未来发展的方向.

Research of Hole Excavated for Building Foundation Precipitation to Environment Influence

The existing hole excavated for building foundation precipitation to the environment impact prediction method may divide into the anal-ysis law, immediately statistical model, artificial intelligence model, with numerical method and other methods, the three dimensional water analo-gy procedure forecast that the hole excavated for building foundation precipitation to environment's will influence be the direction which the furore will develop.
