根据地质勘察报告及相关设计资料,及填海区域地基差异致基础不均匀沉降的特点,对建筑物桩基的选型、试验桩参数等进行了分析,提出了填海地区工程的基础设计方案:场区进行强夯预处理,桩基采用冲孔灌注桩和后注浆技术,以提高桩的承载力,增强桩的稳定性,减小桩基沉降。
Based on the geological survey report and related design data and the uneven subsidence caused by the foundation filling in the reclamation area, the selection of pile foundations and the parameters of test piles are analyzed and the basic design scheme of the reclamation area is proposed : The site is subjected to dynamic compaction pretreatment. The pile foundation is punched and filled and post-grouting to improve the bearing capacity of the pile, enhance the stability of the pile and reduce the settlement of the pile.
