南广高铁路基岩溶整治技术研究

摘要

南广高铁所经的广西地区为岩溶发育地区,岩溶易引起路基不均匀沉降及塌陷.高铁对于路基的沉降等变形控制的要求是极为严格的,因此,高铁岩溶路基的整治施工效果能否满足沉降要求成了关键问题.本文对南广岩溶路基处理进行了技术、经验等成果的总结,力求能够为高铁岩溶路基的整治技术的发展提供支持.%The Nanguang high-speed railway in Guangxi area is karst development area, and the karst can easily cause the uneven settlement and collapse of the roadbed. High-speed rail has extremely strict requirements on the settlement and other deformation control of the roadbed, therefore, whether high-iron karst roadbed remediation construction effect can meet the settlement requirements has become a key issue. In this paper, the technology and experience of Nanning-Guangzhou karst roadbed treatment are summarized, so as to provide technical support for the development of karst roadbed remediation technology.
