宁夏地区深厚湿陷性黄土地基处理方案研究
摘要:宁夏南部地区湿陷性黄土厚度较大，湿陷性系数较大，压缩性高，相应地地基处理难度大，费用高，尤以该地区的低层建筑物地基处理安全性和经济性两者矛盾最为突出，已成为制约该地区开发建设的一大阻碍因素。针对此问题，采用经验总结和专家论证的研究方法，提出采用垫层法部分消除湿陷性，同时采取严格防水措施和结构措施的综合处理方案，以科学、安全、经济和适用为宗旨，经该地区采用此地基处理方案的工程实践证明，此方案能够很好地解决该地区低层建筑物地基处理中安全和经济两者的巨大矛盾，使两者达到协调统一。
Abstract:In the southern part of Ningxia,the thickness of collapsible loess is large,the collapsibility coefficient is large,but the compression index is poor.Correspondingly,the foundation treatment is difficult and costly.Especially,it is most prominent of the contradiction between the safety and economy of the low-rise buildings foundation in this area.It becomes a major obstacle to the development of the region.Aiming at this problem,a comprehensive treatment plan is adopted to partially eliminate collapsibility by adopting cushion method,and stricted waterproof measures and structural measures are taken at the same time.Stricted the results show that the comprehensive treatment plan is scientific,safe,economical and applicable,the engineering practice that used this foundation treatment scheme in this area has proved that this scheme can well solve the huge contradiction between safety and economy in the foundation treatment of low-rise buildings in the area,and take the both achieve harmonization.
