摘要
汕头ＬＰＧ工程的交通洞为一宽７．２ｍ、高５．７ｍ、断面约４０ｍ２、１３．６％下坡道的隧道。１９９８年２月９日当隧道开挖到２４５ｍ处，爆破以后，在隧道底板的右侧突发涌水，其涌水量较大，根据观测约为１５００ｍ３／ｄ。本文主要介绍通过注浆堵水施工的全过程，从而取得可供类似工程借鉴的经验。
The communication cavern of LPG engineering project in Shantou City is a tunnel with the width 7.2 m,height 5.7 m,cross section nearly 40 m 2 and having a down gradient of 13.6%.After blasting during the excavation of tunnel reaching 245 m length at February 9 of 1998,the gushing water occurred suddenly at the right side on the bottom of the tunnel.The capacity of gushing water was rather high,nearly 1500 m 3/d through the observation and test.The paper introduces mainly the whole procedure of the flood protection engineering treatment by grouting in detail,and therefore,provides the experience as a reference for the similar engineering project.
