摘要
湿陷性黄土地区建筑地基基础设计常先采用强夯法或挤密法进行地基处理,后采用柱下独立基础(条形基础)或桩基础。本项目场地约1/3范围分布厚杂填土回填区,设计关键点是湿陷性消除程度、地基与基础的变形控制。通过对建筑结构和地质条件特点分析,提出多种地基基础设计方案,并进行技术经济综合分析,使厚自重湿陷性黄土场地局部厚杂填土复杂地基基础设计安全、经济、合理。
In the design of building foundation in collapsible loess area,dynamic compaction method or compaction method is often used first,and then independent foundation(strip foundation)or pile foundation is used.About 1/3 of the project site is distributed with thick miscellaneous fill backfill area.The key points of design are the degree of collapsibility elimination and the deformation control of foundation and foundation.Based on the analysis of the building structure and geological conditions,a variety of foundation design schemes are put forward,and the technical and economic comprehensive analysis is carried out,so that the design of local thick miscellaneous fill complex foundation in the thick self weight collapsible loess site is safe,economic and reasonable.
