摘　　要：基坑支护关系到水闸工程的安全性。为确保水闸工程的稳定性,需要充分重视深基坑在内的所有设计环节。本文以克孜加尔水闸工程为例,对桩锚支护结构设计方法进行讨论,并对结构设计效果进行数值模拟分析。结果表明:连续介质拉格朗日分析本构模型、支护结构数值计算模型能够比较准确地计算出支护结构的应力分布、横向位移、纵向位移等。Foundation pit supporting is related to the safety of sluice project. All design links including deep foundation pits should be emphasized fully in order to ensure the stability of sluice project. In the paper, Kezi Jia＇ er Sluice Project is adopted as an example for discussing design methods of pile anchor supporting structures. Numerical simulation analysis is carried out on the effect of structure design. Results show that stress distribution, horizontal displacement, vertical displacement, etc. of the supporting structure can be calculated more accurately by the continuous medium Lagrange analysis constitutive model and supporting structure numerical calculation model.
