隧道溶洞處理六招就夠了

隧道溶洞處理，六招就夠了！重要提醒，文中圖片不可編輯!隧道溶洞處理可按巖溶對(duì)隧道的不同影響情況及施工條件，采取引流、跨越、加固、清除、注漿等不同措施或綜合治理。(1)應(yīng)查明溶洞分布范圍和類型，巖層的完整穩(wěn)定程度、填充物和地下水情況，據(jù)以確定施工方法。(2)如巖層比較完整、穩(wěn)定，溶洞已停止發(fā)育，有比較堅(jiān)實(shí)的填充，且地下水量小，可采用探孔或物探等方法，探明地質(zhì)情況。(3)常用處理溶洞的方法，有“引、堵、越、繞”。①引排水遇到暗河或溶洞有水流時(shí)，宜排不宜堵。INCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCO8kSjACTCpOBMeibWszibKvJFaIbGcaT4A1brL6iazIgQ7ic9na7lrMKYg/640?wx_fmt=jpeg"\*MERGEFORMATINET開(kāi)鑿專門的泄水洞將水排出洞外。INCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCApgFtAYfQoQ2XrH8oVC8BDUHnzODgUZg3jbbpfURITibSgTibChiahqIw/640?wx_fmt=jpeg"\*MERGEFORMATINET開(kāi)鑿泄水洞將水排出洞外。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繞行施工在巖溶區(qū)施工，個(gè)別溶洞處理耗時(shí)且困難時(shí)，可采取迂回導(dǎo)坑繞過(guò)溶洞，繼續(xù)進(jìn)行隧道施工，并同時(shí)處理溶洞，以節(jié)省時(shí)間，加快施工進(jìn)度。繞行開(kāi)挖時(shí)，應(yīng)防止洞壁失穩(wěn)。INCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCjUTLbicjueUoVPWa5gO8NF6wWmIrcsVjib1Bj3IPe3LrXliaGWaNtpDDw/640?wx_fmt=jpeg"\*MERGEFORMATINETINCLUDEPICTURE\d"/mmbiz/jcVqjTkf8oxiaGqqYibJWXtQMJ73xX1qTCzeaiacAtjwWibyxpShqm4p3KLkgMIkHgwyQoxUZYW99zRJCJBJvogz8w/640?wx_fm
