简要地介绍了广州市中旅商业城基坑支护及周边建筑物安全监测的成果。中旅商业城基坑挖深达１９ｍ，采用综合支护体系，在基坑周边布置了表面和内部观测仪器，观测了水平位移、沉降、地下水位、锚力等，观测成果表明：基坑的工作状态良好，各监测项目资料规律性较好，基坑边壁及周边土体的最大水平位移为８～２８ｍｍ，小于设计指标，水平位移速度最大为０．６ｍｍ／ｄ，且很快收敛。基坑和周边建筑物是稳定安全的。
Briefly introduced the results of the foundation pit support and surrounding building safety monitoring in the China Travel Business City in Guangzhou. The depth of excavation of the foundation pit of China Travel Commercial City reached 19m. Comprehensive support system was adopted. Surface and internal observation instruments were arranged around the foundation pit. Horizontal displacement, settlement, groundwater level, anchorage force, etc. were observed. Observation results showed that: The condition is good, and the regularity of the data of each monitoring item is good. The maximum horizontal displacement of the side wall of the foundation pit and surrounding soil is 8~28mm, which is less than the design index. The maximum horizontal displacement velocity is 0.6mm/d, and it converges quickly. The pit and surrounding buildings are stable and safe.
