后注浆技术在素混凝土桩复合地基中应用

摘要

Based on a wide review of relevant research home and abroad, the practical merit of the post - grouting technology is investigated according to the case history with the post - grouting. Loading test results indicate that the bearing capacity of the composite foundation increases after grouting in the pile. It has been shown that using the technology ont only can significantly increase the bearing capacity of the pile, but also can achieve good economical benefit Therefore, the technology of post - grouting concrete pile is really an advanced construction technique and deserved to be widely used in the engineering construction.%在调研国内外大量文献的基础上,结合后注浆技术在工程中的应用,对该项技术的实际应用价值进行了探索和研究.实测结果表明后注浆处理后,复合地基承载力得到提高.应用桩端后注浆技术,不仅能够大幅提高承载能力,而且能节省工程造价、获得良好的经济效益.因此,素混凝土桩后注浆确实是一项技术先进、经济合理的施工工艺,值得在工程建设中大量推广应用.
