阿联酋乌姆盖万150MIGD海水淡化厂基础沉降施工控制技术

Foundation Settlement Control Technology for 150MIGD Seawater Desalination Plant in Umm-al-Qaiwain of the United Arab Emirates

阿联酋乌姆盖万150MIGD海水淡化项目的地质条件为典型的沙漠砂土,区域属于典型的热带沙漠气候,降水量少且集中在冬季,砂土的无黏性和颗粒性在雨水渗透和消散下易发生重新排列和水坠现象,导致基础沉降。基于此,文章以该项目为研究对象,分析了基础沉降规律,并提出注浆加固的施工控制措施。研究成果可为阿联酋地区的基础工程施工和加固提供参考,也可为我国沙漠地区的基础工程建设提供借鉴。

The geological condition of 150MIGD seawater desalination project in Umm-al-Qaiwain,the United Arab Emirates is typical desert sandy soil,and the region belongs to typical tropical desert climate.The precipitation is low and concentrated in winter.The non-viscous and granular nature of sandy soil is prone to rearrangement and water falling phenomenon under the infiltration and dissipation of rainwater,which leads to foundation settlement.Based on this,this paper takes this project as the research object,analyzes the foundation settlement law,and proposes the construction control measures of grouting reinforcement.The research results can provide reference for the construction and reinforcement of foundation engineering in the United Arab Emirates region,and can also provide reference for the construction of foundation engineering in the desert region of China.
