摘要
深开挖工程中挡墙变形是引起基坑周围土体变形的重要因素之一。本文用有限元法分析了开挖深度、安全系数、挡墙刚度及土体不排水抗剪强度对挡墙变形的影响，并提出了计算挡墙侧向变形的公式。通过实例说明，本文提出的公式，可供实践参考应用。
The lateral wall deflection is an important cause which results in ground surface displacement and settle-ment around an excavation. This paper examines the influence of a number of factors affecting the lateral wall de-flection in soft一clay using the finite element methed, such as the factor of safety against basal heave,the depth ofexcavation,the wall stiffness and the undrained shear strength of clay.A simplified method to estimate the lateralwall deflection is proposed. Deflections calculated by this method agree fairly with the field records and published da-ta.
