| Abstract: | Combining with the practice of karst treatment in karst area in Jiangshan Section of Hangzhou-Changsha PDL close to existing line, this paper elaborated the construction process of karst treatment by grouting and, in relation to safety, specified related protection measures. Through grouting process for karst, not only the subgrade stability of the new line was improved, but also the effect on the existing Shanghai-Kunming Railway was minimized. Meanwhile, the construction technique created the good conditions for subgrade treatment and guaranteed safe construction and operation. |
