摘要
通过对首都机场北线高速公路桥头地基处理后静载试验和重型动力触探试验数据分析,比较了柱锤冲扩碎石桩、振动沉管碎石桩、复合载体夯扩桩三种不同碎石桩施工工艺的加固效果,对三种工艺的加固原理、适用条件、设计施工应注意的问题进行了分析。
Plate loading test and dynamic penetration test had been conducted on the ground of express highway which lies in north line of Beijing capital airport.Based on the test results,comparison analysis had been carried out for improving effect of three kinds of gravel piles,such as gravel piles thrusted-expanded by column-hammer,vibro-compaction stone columu and rammer-impacting composite material pile.The improving principle,application condition and attention problems for design and construction were also analyzed for these three kinds of gravel piles.
