客运专线铁路对路基变形提出了严格要求,填料改良已经成为客运专线铁路必须解决的问题。研究以动强度为控制条件,以静强度为判别标准的改良土的设计思想,分析了水泥、石灰改良土的特点和使用条件。
The Passenger Dedicated Railway has put forward strict requirements on the deformation of subgrade, and the improvement of packing has become a problem that must be solved by passenger dedicated railway. In this paper, the design idea of modified soil with dynamic strength as control condition and static strength as criterion is studied. The characteristics and operating conditions of cement and lime-modified soil are analyzed.
