研究目的:在铁路或公路隧道施工中,溶洞整治较为棘手,目前成熟方案不多。本文旨在探求铁路或公路隧道施工中溶洞的最佳处理措施。
研究方法:通过319国道江西省萍乡市境内拓村隧道工程实例介绍了采用高压旋喷桩复合地基整治隧道溶洞的整治方案,施工方法及主要施工工艺,并分析了该方法的工艺原理及应用该工艺整治隧道溶洞的质量控制措施。
研究结论:高压旋喷桩复合地基整治整治隧道溶洞,可操作性强,质量及经济效果良好。
Research purposes: In the construction of tunnels for railway and highway, the hole repair is the intractability problem and there are less mature schemes. This paper investigated the best measures that how repair the dissolution caves during construction the tunnel in railway or highway.
Research methods: In this paper, as the zee can tunnels of 319 country highway for example the author introduced the repair scheme of hole with the pile of high pressure and reunite foundation, construction method, construction technology and analyzed the principle and the procedure and the measures in quantity.
Research Conclusions: Using the method that repair the hole with the pile of high pressure and reunite foundation is the better method.
