摘要
依托省道224线二道沟兵站至治多县公路改建工程,综合利用工程地质调绘、地质钻探、原位试验等勘察手段,基本查清沿线连续多年冻土类型、特征及工程地质条件,并针对多年冻土道路常见的翻浆、融沉问题,提出可供选择的工程防治措施。勘察结果为新建或改建公路的线路避绕或治理提供地质依据,也为构筑物结构和基础类型提供必要地质资料。
Relying on the reconstruction project of provincial highway 224 from Erdaogou military station to Zhiduo county,this study comprehensively utilizes engineering geological survey and mapping,geological drilling,in-situ testing,and other survey methods to accurately identify the types,characteristics and engineering geological conditions of continuous permafrost along the lineAiming at the common problems of pulping and thawing of permafrost roads,alternative engineering prevention measures are proposedThe survey results can provide the geological basis for the route avoidance or treatment of the reconstructed highway and provide the necessary geological data for the structure and foundation type of the structures。
