微型钢管灌注桩桩基挡墙承载力分析

Bearing Capacity Analysis of Retaining Wall Based on Minisize Bore-hole Steel Tube Driven Cast-in-place Piles

依据福银高速公路某桥台锥坡滑坡抢险工程中采用微型钻孔钢管灌注桩桩基挡墙的工程实例,分析钢管灌注桩承载力特性。采用三种不同计算模式对该新型结构的桩基水平承载力进行计算,确定符合实际工况的最优计算模式,对同类型承受水平荷载的工程有一定参考意义。

The bearing capacity character of retaining wall based on minisize bore-hole steel tube driven east-inplace piles has been analysed according to the ease of landslide treatment on some quadrant of truncated cone in Fu Ying expressway. Three models have been used to calculate the horizontal bearing capacity of pile foundation of the new structure. The suitable calculating model is decided, that will be valuable to the similar project.
