引言工程地质和水文地质是顶管施工前必须详细了解的问题之一,也是决定顶管施工成败的关键因素。本文试就土壤在顶管施工中的地位、土壤在顶管施工中的分类,以及采用的物理力学性能指标、不同土层的分布状态及对顶进中的影响、特种土壤中的顶进措施、以及施工的难易程度的划分等问题进行讨论。
Introduction Engineering geology and hydrogeology are one of the issues that must be understood in detail before the construction of the pipe jacking, and are also the key factors that determine the success or failure of pipe jacking construction. This paper examines the status of soil in pipe jacking construction, the classification of soil in pipe jacking construction, the physical and mechanical performance indicators used, the distribution status of different soil layers, the impact on jacking, and the jacking measures in special soils. , as well as the division of the degree of difficulty in construction and other issues discussed.
