沟谷区域高填方诱发桩基建筑倾斜机理研究

The mechanism of Building Inclination with pile foundation induced by High Embankment in Gully Area

以福建沟谷区域的某高填方建筑工程项目为例,根据沟谷原状地形和填方施工资料,采用三维数值分析方法,研究了填方施工对建筑及基础的不利影响。结果表明:高填方引起的负摩阻力及侧向土压力是诱发建筑倾斜的主要原因。本文的倾斜计算结果与监测数据十分吻合,对于研究填方坡地建筑倾斜机理及纠偏治理具有较大的参考价值。

Combining with the project example,the mechanism of building inclination with pile foundation induced by high embankment was researched by numerical simulation.The results show that:the negative friction and horizontal force induced by high embankment is the key reason that building inclined.The results are consistent with the monitoring data,and can provide some reference to investigating the mechanism of building inclination and correction.
