摘要
随着高层建筑和地下空间工程的发展,涌现了大量的深基坑工程,有明显的场地限制和严格的变形控制要求,而双排桩作为一种新型的支护结构,具有侧向刚度大、能有效限制侧向变形、便于挖土和缩短工期等优点,支护效果明显。结合工程实际应用,说明双排桩的支护设计方法和施工方便、挡土结构受力条件好、保持基坑稳定等优点,并取得了良好的支护效果。
With development of high building and underground space works, the deep foundation pit works occurs in a large quantity, which are with obvious site restriction and strict deformation control requirement.As a new support structure, the double-row piles are with high lateral rigidity, convenient for excavation as well as can effectively restrain lateral deformation and shorten construction period. The support effect is significant.In combination of engineering practice, design of double-row piles support as well as features of conven-ient construction, good action condition of the retaining structure, and keeping stability of the foundation pit are described.An expected support effect achieved is demonstrated .
