| 摘 要： | 通港大厦基础埋深－１６．９３０ｍ，施工场地狭小，周围管线复杂。经方案比较后，决定采用锚喷网支护廊，施工中对渗水严重部位设置内部排水系统，雨期及时处理隐患部位并及时量测支护变形和裂缝。支护完成后的测量结果为：边坡最大水平位移５０ｍｍ，最大沉降量２０ｍｍ，均满足安全要求。

| Abstract: | The underground foundation depth of the Beijing Tonggang Mansion project is -16.930 m.Its construction site is narrow while its surrounding pipe-lines are complicated.After a comprehensive comparison and deliberation of construction plans,the spurt-anchor network technology for deep foundation strut construction has been adopted finally.During its construction ,an internal drainage system is arranged at the serious leak sections.Its hidden troubles sections have been promotly treated in rainy day and its cracks and strut deformation have been immediately investigated and checked.The survey has shown that the slope' s maximum horizontal displacement is 50 mm and maximum settlement is 20 mm ,both of them have been proved satisfactory in security requirement. |
