摘要
岩溶路基在高速公路修建过程中极易产生失稳破坏。以武深高速公路TJ05标丹霞枢纽互通主线1#桥上跨韶赣高速公路为研究对象,对韶赣高速公路岩溶路基进行检测,基于检测结果,结合理论对岩溶路基稳定性进行分析,并对其整治技术进行探究。对岩溶路基的检测、理论分析、稳定性研究及整治技术的系统性研究可为岩溶路基失稳整治提供借鉴。
the karst roadbed is prone to destabilization during the construction of expressway.Taking the Shaogan expressway crossing under No.1 bridge between the main line of TJ05 and Danxia junction of Wushen expressway as the research object, making CT test of Shaogan high-speed karst roadbed, analyzing the stability of karst subgrade based on the test results and theoretical analysis, and studying its treatment technology. The systematic research on the detection, theoretical analysis, stability research and remediation technology of karst roadbed can provide reference for the instability of karst roadbed.
