摘要:
近年来，顶管施工方法因其扰动小、工期短等显著优势，逐渐应用于隧道工程中。鉴于其实用性，很多学者对开挖效应对管道及土体的影响规律进行了探究，目前的研究多采用有限元软件进行，而传统有限元方法无法完成大变形计算。针对这一问题，本文基于重庆某顶管工程，采用一种新的数值模拟方法物质点法进行了数值计算，该方法合理调整网格密度并同经验公式进行对比，验证可靠性之后，调整土层强度参数，探究不同土质下顶管施工对土体沉降量的影响规律，并据此研究顶管施工的适用性，可为工程建设提供参考。
Abstract:
In recent years, pipe jacking construction method has been gradually applied in tunnel engineering because of its obvious advantages such as small disturbance and short construction period. In view of its practicability, many scholars have studied the influence law of excavation effect on pipeline and soil. At present, most of the studies are carried out by finite element software, but traditional finite element method cannot complete large deformation calculation. In order to solve this problem, a new numerical simulation method- material point method is adopted to carry out numerical calculation based on a pipe jacking project in Chongqing. This method adjusts the grid density reasonably and compares it with the empirical formula. After verifying the reliability, it adjusts the soil strength parameters and explores the influence rule of pipe jacking construction on settlement of soil under different soil conditions. According to above simulation calculation result, the applicability of pipe jacking construction is studied, which can provide reference for engineering construction.
