摘要
隧道渗漏是隧道工程施工中普遍存在的质量问题,高寒地区隧道因冻胀而引起渗漏更为突出。结合318国道(川藏公路)拉纳山隧道施工实例,探讨高寒地区隧道易导致发生渗漏的衬砌环接缝处、防水板施工、堵裂隙水、排水措施和抗渗混凝土施工等几个方面施工中的预防措施。
Tunnels＇ water seepage problem is quite common in tunnel digging projects, especially at high altitude and low temperature area because of freezing and expansion. Taking Lana mountain tunnel of 318th national highway as reference, this article analyzes and discusses reasons for water seepage in several aspects such as water freezing at seams, cover flashing, blocking water from cranny, drainage and anti-seep beton, etc, and provides relevant preventive methods.
