摘要
在软土地区,围护桩桩间流土对基坑周边环境产生较为显著的影响。结合具体基坑工程实例,针对桩间流土对基坑变形性状的影响进行较为深入的探讨。桩间流土对基坑变形的影响存在显著的空间效应,且阳角区域处的影响程度显著大于阴角区域处。桩间流土不仅会影响基坑开挖面以上部分深层土体的位移,而且对开挖面以下一定深度范围内的土体也产生一定影响。桩间流土主要对双排桩的前、后排桩之间的土体产生影响,而对后排桩的桩后土体影响较小。
In soft soil, the soil surrounding environment. Based loss between the bracing piles has a on engineering practice, the influence more significant impact on the of the soil loss between piles on the deformation characteristics of foundation excavation is analyzed. The influence of the soil loss shows significant spatial effect, that the influence degree on the positive corner is significantly larger than the negative corner. The soil loss will not only affect the displacement of the soil above the excavation section, but also affect the displacement of the soil below the excavation section within a certain depth range. The soil between the front and rear piles of double-row piles is affected by the soil loss, but the soil behind the rear piles is less affected.
