摘要市政管线受工程堆载的影响会产生附加应力和变形，甚至开裂破坏。从工程堆载的地层响应角度出发，将堆载作用在管线上的表观荷载分为直接应力形式和位移形式两种，基于响应机制不同，给出相应的修正Winkler地基模量表达式，并考虑非连续接口管线的力学特性，提出地面堆载下市政地埋管线响应的Winkler模型简化计算方法。通过与模型试验和有限元模型的对比验证所提方法的合理性，并进一步由参数分析得到土体模量、接口刚度变化对地埋管线纵向响应的影响。研究成果可为市政管线的维护提供理论支持。

Abstract：The construction load causes extra deformation and bending moment on nearby buried municipal pipelines，even damage. Simplified theory for longitudinal response of municipal pipeline under construction load is given，based on the Winkler subgrade model and consideration for the mechanical property of joints of discontinuous pipelines. The effects of extra stress and soil displacement are considered respectively from different mechanism，and soil-pipeline interaction parameters are revised. The rationality of the method is verified by comparisons with model tests and finite element method. Then the parametric study is conducted to investigate the influence of soil elastic modulus and the joint stiffness on the behavior of pipeline due to nearby construction load. The research provides theoretical support for the long-term maintenance of municipal pipelines.

Key words： soil mechanics construction load municipal pipelines Winkler subgrade model model test discontinuous joint
