摘要
广州白云国际机场综合交通枢纽项目所在场区溶(土)洞较发育,对其地下工程的施工质量和安全影响较大。主要从处理原则、处理范围、处理材料及工艺、效果验证等方面,介绍了本项目基础工程中的溶(土)洞处理技术,并从降低施工过程安全风险、改善地基承载力和地基稳定性、预防溶(土)洞进一步发育对地下工程产生不良影响等方面考虑,建议地下工程实施前应对已发现的溶(土)洞进行处理。
The integrated transportation hub project of Guangzhou Baiyun International Airport is located in the area where the dissolved soil cave is relatively developed,which has a great influence on the quality and safety of the underground construction.This article mainly introduces dissolving（soil） hole processing technology of the foundation engineering solution from the processing principle,processing,processing materials and technology,effect of verification,and considering from the aspects of reducing the safety risk of the construction process,improving the bearing capacity of the foundation and the stability of the foundation,preventing the further development of the dissolving（soil） hole and causing the adverse effects on the underground engineering.It is suggested that the dissolving（soil） hole should be dealt with before the underground project is put into operation.
