粘土层大跨度隧道施工

摘要

Combining with engineering example, the thesis studies large-span tunnel construction technology of clay layer, mainly explores barrel construction technology, and introduces barrel support, spaying concrete and barrel masonry and other points, and analyzes waterproofing and drainage measures of barrel entrance and major barrel, which has accumulated experience for similar engineering construction.%结合工程实例，对粘土层大跨度隧道施工技术进行了研究，着重探讨了洞身的施工工艺，对洞身支护、喷射混凝土、洞身衬砌等环节作了详细介绍，并分析了洞口与正洞的防排水措施，为同类工程的施工积累了经验。
