斜锚桩在锚桩法静载试验中的应用

Application of inclined anchor pile in static load test of anchor pile method

锚桩是锚桩法静载试验系统中极其重要的组成部分,一般采用直桩。对没有直桩只有斜桩的工程进行静载试验是工程界碰到的问题。文中介绍了斜桩作锚桩在基桩静载试验中的应用,利用8根倾斜度为5∶1的斜桩作锚桩,利用斜桩本身截下的桩头做拉帽,既达到了静载试验的目的又避免造成工程桩变形。通过工程实践证明,采取适当的措施斜锚桩在静载试验中完全可行,采用斜桩作锚桩具有良好的实用价值,在斜桩工程中节约了工程造价,可为斜桩工程基桩静载试验提供借鉴参考。

Anchor pile is an important part of anchor pile static load test system, and the straight pile is generally used as the anchor pile. It is a problem in engineering field to carry out static load test for the project without straight pile and only inclined pile. We introduced the application of inclined pile as anchor pile in static load test of foundation pile, using 8 inclined piles with a slope of 5:1 as anchor piles, using pile head cut off by inclined pile as pull cap, which achieves the purpose of static load test, and avoids the deformation of engineering pile. Through the engineering practice, it is proved that taking appropriate measures is feasible in the static load test of the inclined anchor pile, and it has good practical value to use the inclined pile as the anchor pile, which saves the engineering cost in the inclined pile project, and can provide reference for the static load test of the foundation pile of the inclined pile project.
