摘要
重庆世界贸易中心5层地下室的侧墙、底板与岩石紧贴连成一体，结构尺寸大且未设伸缩缝，为减小两者之间的约束系数，设置滑动层构造。在山区岩石地基中应遵循“减少约束、防止开裂、多道防线、刚柔结合”的设防原则，可防止结构混凝土开裂，达到无渗漏的质量要求。
The monolithic body made of side - wall, foundation - bed and rock of a 5 - storey deep basement of the Chongqing World - Trade Centre pro-ject, has been designed of a large - scale dimension structure without any expan-sion joint.However, there is a sliding layer designed purposely to reduce its re-straint pressure.In the foundation design in a mountainous region, it is necessary to abide by the universal principle, i.e. 'The proper reduction of restraint pres-sure, the strict prevention of crack, the multiple protective lines against disaster,and the integration of rigidity and flexibility methed'. As a result, it has prevented concrete structure's crack and achieved a fine quality of watertightness.
