| 中文摘要: |
| 粉细砂地层砂层松散，无粘聚力，自稳能力很差，在该地层中开挖隧道极易发生涌水、涌砂、塌方等工程灾害，因此含水粉细砂地层的施工，是岩土工程界的一大难题。结合工程实际介绍未成岩地层中隧道施工技术，并按照“先降水、管超前、严注浆、短进尺、强支护、早封闭、勤测量、紧衬砌”的施工原则，着重介绍粉细沙岩含水地层斜井和交岔口段进行降水及开挖的施工技术。 |
| 英文摘要: |
| The moisture fine silt stratum, which is loose, without adherence, has poor stabilizing ability. Streaming water, running sand and collapse etc，often take place while excavating tunnel in such stratum. Therefore, the construction in the moisture fine silt stratum is a hard nut to crack. This paper introduces tunnel construction technique in non rock stratum, and in accordance with the principle of “first dewater, pipe in advance, strict grouting, short footage, strong support and early close, frequent measurement and tight lining”, introduces emphatically the dewater and excavation construction technology at slope well and intersection section in the moisture fine silt stratum. |
