［摘要］廣州金融城起步區(qū)共分七個組團，地下空間總建筑面積約為213-6萬m2，大型地下空間的漏水問題一直是困擾工程設計人員的一個難題。首先分析結構主體的防水性能，分析結果表明，各組團內部的地下室可采用不設永久變形縫的方案，其中方城組團的地下連續(xù)墻＋疏排水層的防水方案，便于多個建設單位分別開發(fā)，防水效果較好。然后給出了組團間變形縫、等易漏水部位結構細部防水做法。最后從設計、施工、材料等方面給出了保障結構主體防水性能的裂縫控制措施。以便在防水方面保障廣州金融城起步區(qū)地下空間的使用。

Abstract:There are seven plan areas in Guangzhou Financial City Starting District, with the total construction area of 2-136 million m2 in underground space. And leakage in large space basement is always a big problem in design process. Firstly, the waterproofing performance of the main body of the structure was analyzed. The analysis results show that the scheme without permanent deformation joints can be adopted in the basement of each group. The waterproofing scheme of diaphragm wall + drainage layer in Fangcheng plan area is convenient for several construction units to develop separately, and the waterproofing effect is better. Then, the waterproofing methods of the deformation joints between plan areas and the structural details of the leaky parts were given. Finally, from the aspects of design, construction and material, the crack control measures were given to ensure the waterproofing performance of the main structure, in order to protect the use of underground space in Guangzhou Financial City Starting District.
Keywords:Guangzhou Financial City Starting District; large underground space; structural waterproofing; structural main body; structural details; concrete crack
