一、工程概况 中国工商银行广东省分行业务大楼位于广州市沿江西路与新堤三横路交界处的西北角,地理位置显赫,交通四通八达,商业繁茂,是广州市最为理想的商业办公中心,由于其紧靠珠江和爱群大厦这一文物建筑,其完成之时也将是广州风景建筑的组成之一。本工程设计楼高二十九层,地下室五层,基坑开挖深19.2m,是广州乃至全国最深的地下室基坑之一。加上本工程所处位置、地质状况和周围环境等各方面的条件,使本工程成为一个技术难度相当大的地下室工程。本工程占地面积2115m~2,其中地下室建筑面积9518.0m~2,施工场地基本为零,更为复杂的是基坑四周全部都是要特别保护的建筑物或马路及地下市政管线设施。施工环境平面如图所示:
I. Project Overview The Industrial and Commercial Bank of China branch in Guangdong Province is located in the northwest corner of the junction of Yanjiang Road and Xindi Sanheng Road in Guangzhou. It is an ideal commercial office center due to its outstanding geographical location, convenient transportation and lush commercial facilities. Close to the Zhujiang and Aiqun Building, this heritage building will also be one of the components of the Guangzhou landscape architecture. The project is designed to have a height of 29 floors and a basement of 5 floors. The excavation depth is 19.2m. It is one of the deepest basement pits in Guangzhou and even in China. In addition, the location of the project, the geological conditions and the surrounding environment and other conditions make this project a basement project with considerable technical difficulty. The project covers an area of 2115m~2, of which the basement building area is 9518.0m~2. The construction site is basically zero. Even more complicated is that all the perimeters of the foundation pit are buildings or roads and underground municipal pipeline facilities to be specially protected.
