摘　　要：管井降水能疏干基土中的水分,加速土体固结,提高地基强度。还可以减少土坡土体侧向位移与沉降,稳定边坡,消除流砂,减少基底土的隆起,避免位于天然地下水以下的地基与基础工程施工受地下水影响,提供比较干的施工条件,提高工程质量,保证施工安全。以乌兹别克斯坦布哈拉州市中心的布哈拉调控中心项目为例,研究管井降水方案实施过程、质量保证措施、HSE保证措施。研究表明,在渗透系数较大的地区,使用管井降水能取得良好的效果。The dewatering of the pipe well can reduce the water in the dry base soil,accelerate the consoli-dation of the soil,and improve the strength of the foundation while at the same time avoiding slope lateral displacement and subsidence,enhancing slopes stability,removing sand flow and reducing the soil lifting effect in foundation,preventing possible negative effects of ground water on foundation construction below the natural ground water level and ensuring the availability of dry construction conditions with reduced soil volume and shorter construction duration,thus improving overall project quality and providing construction safety.This paper takes Bukhara Dispatch and Control Center Project as example,and analyzes the implementation of dewater measures,the measures of quality assurance and HSE.The results show that good effect can be obtained for pipe well dewatering in the areas with large permeability coefficient.
