天津地区淤泥类土对桩基质量的影响规律及防治方法

Discussion on Effect Pattern of Sludge in Tianjin Area on Pile Quality and on Preventive Methods

天津地区表土层中广泛分布着较厚的淤泥类土。由于该层土特殊的工程地质特性,其在对建(构)筑物的桩基施工质量上有着较大的危害性。通过对以往工程中的桩基缺陷与其对应的勘察资料进行了粗略的统计和分析,寻找出了淤泥类土对桩基质量影响的一定规律,对今后工程中防止桩基缺陷提出了指导性建议。

There is a lot of sludge in pedosphere of Tianjin Area. Because of the geological characteristics of the sludge, it is dangerous to the quantity of piles within it. After analyses on and comparison between the defections of piles and geological data, the effect pattern of sludge on pile quantity was got out. Some suggestions about pile defect prevention in future project were put forward.
