补充资料:基坑涌水
建筑物基坑开挖深度低于地下水位引起地下水涌入基坑的现象。涌入基坑的水一般来自围岩和坑底。如果基坑底面以下浅部有承压含水层,随着基坑开挖深度增加,承压含水层顶部不透水层的厚度不断减小,强度不断降低,当含水层水头压力大于不透水层强度时,承压水则冲破基坑坑底而涌入基坑中。基坑涌水有时会使坑壁失稳,或因坑壁岩、土体发生机械潜蚀,导致突发性大量涌水而淹没基坑,给施工带来极大困难。
直接影响基坑涌水量的因素有:地下水补给来源及其至基坑的距离;地区大气降水强度、延续时间和入渗系数;基坑围岩的渗透通道、含水层厚度、埋藏深度和围岩的渗透系数等。
为了避免基坑涌水给施工带来困难,基坑开挖前应对可能发生涌水的基坑进行涌水量预报,并根据当地水文地质条件和预报的涌水量,采取适当的防治措施。对于涌水量一般较大的水工建筑物,可采用防渗帷幕或设置抽水井、孔等工程措施。对于涌水量不大的建筑基坑,可选用适当排水能力的水泵抽排;在饱水砂土中施工时,还可采用人工冻结方法。
