摘要
软土地区建设难度大,地基处理作为建设项目的重中之重,其施工质量的好坏关系着整个项目的最终成败,而其地基处理技术是否完善与合理,直接关联着施工质量水平.随着地基处理技术的不断发展,越来越多的新型工艺被广泛应用于工程建设中,其中,灌注桩后注浆技术作为软土地基处理中的重点技术,其发展也是日新月异,虽然该工艺理论不断完善,但实际施工中要实现其理论要求与实际施工达到的效果相一致是比较难的,因此有必要针对灌注桩后注浆技术的施工工艺开展研究.
Abstract
With the fast development of the infrastructure construction,foundation construction difficulties are encountered at different geological areas with the most difficulties in the soft soils.Among these,the ground improvement in the soft soil areas is the most important and is critical to the entire construction quality.The post grouting technique for the bored and cast-in-place concrete piles is more and more applied in the construction.This paper presents the state-of-the-art review of the post grouting mehtods.
