摘要
由于吹填造陆等原因,沿海工程桩周围存在不平衡的堆载现象,大面积填土对桩基产生负摩阻力、被动桩和土体蠕变效应3个关键问题。本次吹填区不平衡堆载试验结合台州湾大桥工程试桩进行,在桩间和土中埋设测斜仪,测出边桩、中桩及土体的位移,分析吹填区不平衡堆载对桩基的影响,可为类似工程提供参考。
Due to reasons such as hudraulic reclamation,coastal engineering pile often encounters imbalanced surcharge load caused by new reclamation area. The impact of pile foundation caused by large area filling load mainly focused on three key questions：the passive pile, negative skin friction resistance and soil creep effect problem. This paper introduces the imbalance load test of Taizhou bay bridge engi- neering pile. To measure the inside displacement of the side pile, the middle pile and the soil by inclinom- eter,the effect of reclamation area on pile foundation was analyzed, which can be referenced by similar projects.
