摘　　要：在隧洞施工中进行安全监控量测是必不可少的。通过对重庆主城排水工程CQWW2.01标段57#～61#隧洞施工监控量测结果的分析,介绍了复杂环境条件下围岩为砂质粘土隧洞施工监控量测的基本方法,总结出该类隧洞及地面变形的基本规律,对今后类似工程的施工监测提供重要的参考价值。It is necessary to adopt safe monitoring and measuring in tunnel construction. The construction measured results of marked tunnel section 57 - 61 of drainage system of the tender CQWW2.01 in Chongqing City are presented. Based on the analysis of the measured results, the basic methods of supervisory measurements on tunnel construction under the complex conditions that surrounding rocks are mainly sandy clay are introduced; and the basic deformation regularity of similar tunnel and ground are also summarized. The achieved experience and data can be for reference to the construction and research of similar tunnels.
