| 摘 要： | 文章主要介绍宜万铁路野三关隧道DK124+602高压富水溶腔的规模与处治技术.602溶腔影响隧道纵向达20 m,向上与3号暗河连通,最大涌水量48万m3/d,实测水压1.0 MPa.该溶腔段施工采取了高位排水降压、帷幕注浆、管棚预支护等技术措施,实现了降压、加固、堵水、肪渗的目的,防止高压渗水直接传递给隧道结构,为隧道开挖通过溶腔及运营结构安全提供了重要保障.

| Abstract: | The paper introduces the scale and treatment technology of the high pressure and water-soaked karst cave at DK124 +602 in Yesanguan Tunnel onYichang -Wanzhou Railway. 602 karst cave affected the tunnel longitudinally amount to 20 meters, connecting up with the No.3 underground river, whose largest water flow reached 480000m3/day with measured water pressure 1.0 MPa. In the construction of the tunnel section through the cave high level drainage of water was carried out to drop high pressure, curtain grouting... |
