Abstract：
Considering high underground water level and abundant underground water resource in Cangzhou City, large diameter tube well dewatering technique is adopted in the annular foundation pit in which the dewatering area is large and whose radial width is large. The design is carried out by intercepting computing element. With references to overall factors and construction experiences of adjacent projects, the dewatering well is arranged in three rings, including internal ring, middle ring and external ring. Dewatering effect is successfully ensured and engineering dewatering cost is obviously reduced through in-depth design and optimization of waterproof work.
