沙特近海典型沙漠地质条件下的深基坑降水方法

摘要

结合工程实例对沙特朱拜勒冷却水工程的泵房深基坑降水方法进行了详细介绍，对轻型井点和明排两种降水技术的结合、创新应用进行了阐述，全面验算和验证了在沙特近海典型沙漠地质条件下深基坑“1.5级轻型井点+护脚明排”降水方法的有效性。%Combined with engineering project, we made a detail description for the dewatering method of deep excavation in Saudi Jubail seawater cooling project, introduced the combination and the creative application of light well point drainage and blind drainage, and proved that the dewatering method of"1.5 light well point+banket and blind drainage"is feasible in deep excavation of Saudi coastal desert geology.
