摘要: 承插式管廊接头是地下综合管廊接头的常用结构形式,其受力性能及破坏形式对工程设计和施工至关重要.利用非线性有限元软件ABAQUS建立土-地下综合管廊结构数值模型.将管廊划分实体单元,提取接头处结点的变形量及应力值,研究管廊及管廊周围土体的应力分布和变形规律,最后通过计算得出管廊接头处的延性系数及开裂荷载.通过数值模拟和理论计算分析得出管廊接头处存在的安全隐患及其潜在破坏模式,为解决接头处的防水问题和不均匀沉降问题提供理论参考.

关键词: 地下综合管廊, 接头位置, 应力集中, 结构变形, 破坏模式

Abstract: The bell and spigot joint is the common structure form of the utility tunnel joint, and its mechanical properties and failure modes are very important for engineering design and construction. First, a numerical model for soil and underground utility tunnel was established by using nonlinear finite element software ABAQUS; then, the utility tunnel was divided into physical unit elements and the stress distribution and the deformation law of the soil and the utility tunnel were studied by extracting the deformation amount and the stress value of the nodes at the joint; finally, the ductility coefficient and the cracking load of the utility tunnel were calculated. Through numerical simulation and theoretical calculation, the potential safety hazards and damage patterns of the joints in the tube gallery were obtained to provide some theoretical references for waterproofing and uneven settlement control.

Key words: utility tunnel, joint position, stress concentration, structure deformation, failure mode
