| 摘 要： | 桩底通过注浆提高地基承载力的施工工艺,在工程建设中正得到逐步推广,对改善特定地质条件下桩基的承载力和减少桩基长度非常明显,可大大改善桩基受力,同时缩减桩身长度,避免长桩施工遇到困难,解决了桩端沉渣残留的难题,还缩短了工期,节省了大量的建设资金,相信该技术在不断完善中会得到更广泛的应用.

| Abstract: | Pile-bottom grouting technology is used more and more in reinforce subgrade for bridge construction, which can lower bear force of pile foundation in certain condition and reduce the length of pile obviously. And it also has many advantages, such as avoiding the difficult for long pile, resolving the problem of pile wasted, shorten construction period and saving construction cost. So, we believe the technology will be widely used in the future. |
