盘岭公路隧道涌水突泥治理措施

摘要

鉴于公路隧道涌水突泥地质灾害具有危害大、治理难的特点，以贵州省三穗至黎平高速公路盘岭隧道为背景，阐述了隧道右洞第一次、第二次涌水突泥过程和治理措施及效果，2次分别采用超前管棚注浆、全断面帷幕注浆加固围岩，治理效果前者欠佳、后者显著。%The geological disaster of water bursting and mud gushing in highway tunnel is greatly harmful and difficult to control.Taking the section from Sanhui to Liping of the Panling highway tun-nel in Guizhou province as the background,the results and treatments of the first and the second time of water bursting and mud gushing process in the right hole are investigated.It is shows that the re-sult of full-face curtain grouting treatment is better than that of the lead pipe-roof grouting treatment.
