隧道溶洞处理六招就够了

隧道溶洞处理，六招就够了！重要提醒，文中图片不可编辑!隧道溶洞处理可按岩溶对隧道的不同影响情况及施工条件，采取引流、跨越、加固、清除、注浆等不同措施或综合治理。(1)应查明溶洞分布范围和类型，岩层的完整稳定程度、填充物和地下水情况，据以确定施工方法。(2)如岩层比较完整、稳定，溶洞已停止发育，有比较坚实的填充，且地下水量小，可采用探孔或物探等方法，探明地质情况。(3)常用处理溶洞的方法，有“引、堵、越、绕”。①引排水遇到暗河或溶洞有水流时，宜排不宜堵。INCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCO8kSjACTCpOBMeibWszibKvJFaIbGcaT4A1brL6iazIgQ7ic9na7lrMKYg/640?wx_fmt=jpeg"\*MERGEFORMATINET开凿专门的泄水洞将水排出洞外。INCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCApgFtAYfQoQ2XrH8oVC8BDUHnzODgUZg3jbbpfURITibSgTibChiahqIw/640?wx_fmt=jpeg"\*MERGEFORMATINET开凿泄水洞将水排出洞外。INCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCGT7hAO9mpPlSdW4NrI8Fc8icDrTIh8NXxXDZCegfyicSu7WnHNJIbUhQ/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCiaw9ZjkSyhq2pomkAklNZFp3g6Fp6egXsicv14moFGrODEqmnNKzU3hA/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCJeASibsxMx9F7D9voy1OwViaX5RXehGnmLoGfc1rwcPL03BUM7EDR9Tw/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCGAFWwvCVCE6BYOnDTa4eVG1mYjtl5eOXan8k4ZavsLibHZX9DXmMicjw/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCt6AicOAGXEKJGVnCTia4tpws70N66JdlO5wa4yM1ialda6s2Kzc4hvTOQ/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTChRQXxpC1Lf47oUiaSk11Wibru3p8gTUrLRQZibPjPNa2LWHGia6uicm2rEA/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCEDnianQZLLbGGf5kiaic5roH248tPOkXicpxKZY7nxTnRcBwIVq39FTrrw/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCj4a5NzJZkfZ1tYeWrRYCfXEROhejicO2icKU8nJm3zKssGng7SA4nxdw/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCMAoAjfOmXBv4th2ibEtEib2BhbIMicc2YLNXKocYUWlmaKxJKeHL88rog/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTC4YmBPeoMwDA0ckIzictVInjiax6ShCJic8eaJfV9TWqMx4UCYNct6vrAQ/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCEyfOtMYOKDymu7iarqCrZcb6qToLwYvOurK2EvKnddofLOtsnzuPJ5w/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCZ3Kte2ibpqCGbnTxwRxxQfdhBo7EJWT6PhwSSbbe6ibmCu6V2AjdsR9w/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCHyt2BydfSOfqXplEGO22vUHLaJeHfojpk7OcyhUobtA1gAcnmJLbEQ/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCjqm0fWoDD5jD7XPAIdenSVr3cpnI3VqhcDhFiboDicy1JTFJ8cfcGeGg/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTC8z9QCYJT9rLvwLavnOmwPVQoKEyldc0m8NpwYDmiarEvywlcsJelRRA/640?wx_fmt=jpeg"\*MERGEFORMATINET⑤绕行施工在岩溶区施工，个别溶洞处理耗时且困难时，可采取迂回导坑绕过溶洞，继续进行隧道施工，并同时处理溶洞，以节省时间，加快施工进度。绕行开挖时，应防止洞壁失稳。INCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCjUTLbicjueUoVPWa5gO8NF6wWmIrcsVjib1Bj3IPe3LrXliaGWaNtpDDw/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCzeaiacAtjwWibyxpShqm4p3KLkgMIkHgwyQoxUZYW99zRJCJBJvogz8w/640?wx_fm
