摘要
北涯隧道位于广西河池附近峰林谷地地貌区,岩溶极发育,施工中共揭示5处大型溶洞,各溶洞形态及发展阶段不同,充填物性质及厚度也不一致。结合施工过程叙述各溶洞形态及规模,分析洞内充填物性质,简要分析岩溶发展过程,重点介绍了各种处理措施。
Beiya Tunnel is located in the geomorphologic region close to Hechi, Guangxi featuring peak and valley. The karst is developed there and five large karst caves were found during construction. The forms and development stages of the caves are not the same and nor do the nature and thickness of the filling materials. Combining with construction period, the forms and scales of the caves are described ; the nature of the filling materials inside the caves are analyzed; the developing process of the karst is analyzed simply; and the various treatment measures are introduced emphatically.
