摘要：顶管工程作为一种非开挖施工技术，在城市基础设施建设中得到了广泛应用。而顶管施工过程中对周边环境的影响，尤其是土体变形和沉降问题，一直是工程界关注的重点。本文通过数值模拟方法，系统研究顶管工程施工对周边环境的影响。本文简要介绍了顶管工程的基本概念和施工流程。随后，基于有限元基本原理，建立了顶管施工的数值模型，并通过模拟分析了施工过程中土体的变形情况。结果表明，顶管施工会引起明显的土体沉降，且沉降量与覆土高度密切相关。进一步，本文通过数值模拟，详细分析了顶管施工对周边环境的影响，包括地表沉降、建筑物变形等。研究结果显示，覆土高度对土体沉降的影响显著，覆土高度越低，沉降量越大。
Abstract: Top pipe engineering, as a non -excavation construction technology, has been widely used in urban infrastructure construction. The impact of top pipe construction on the surrounding environment, especially the problem of soil deformation and settlement, has always been a focus of attention in the engineering community. This article systematically studies the impact of top pipe construction on the surrounding environment through numerical simulation methods. This article briefly introduces the basic concepts and construction process of top pipe engineering. Subsequently, based on the basic principles of finite element analysis, a numerical model for top pipe construction was established, and the deformation of the soil during the construction process was analyzed through simulation. The results indicate that top pipe construction can cause significant soil settlement, and the amount of settlement is closely related to the height of the overlying soil. Furthermore, this article analyzes the impact of top pipe construction on the surrounding environment in detail through numerical simulations, including surface settlement, building deformation, etc. The research results show that the height of overlying soil has a significant impact on soil settlement, and the lower the height of overlying soil, the greater the settlement.
