微型桩原型水平荷载试验研究

PROTOTYPE TESTING STUDY ON MICROPILES UNDER LATERAL LOADING

对软土地基中的微型桩单桩及群桩进行了水平荷载试验,并对试验结果进行了分析。试验结果表明,微型桩有较好的抵抗水平荷载的能力,尤其是斜桩基础能有效地减小水平荷载引起的位移。应用p-y曲线法计算了单桩和群桩的水平位移,计算结果与实测值接近。

Prototype testing study is made on single micropile and micropile groups under lateral loading in soft soil. The test results indicate that the micropiles are of good ability to resist lateral loading and especially the inclined piles reduce the deflections caused by lateral loading effectively. The lateral deflections of single pile and pile groups are computed by the p-y method and the computation results agreed well with test results.
