Abstract
This paper summarizes the formation, development and improvement of subgrade technical system and addresses the achievements in the past decade in terms of foundation treatment; subgrade structural design and reclamation; embankment cut; transitional section; support and water proof for subgrade slope;integrated foundation of subgrade structure with auxiliary cable channel and catenary post pit;observation and evaluation of settlement deformation. It is the high speed railway, which sets high requirements for subgrade engineering rigidness and deformation control, that has resulted in innovation and improvement of subgrade technology, in reinforcement of subgrade structure engineering concepts and prolonged life cycle of subgrade structures. The remaining problems are explained in perspectives of non-saturated soil and swelling soil encountered in subgrade engineering. It is hoped that this paper may serve to promote the improvement and development of subgrade technical system and the level of subgrade construction, and further vitalizes the operation of high speed trains in a safer, higher speed and more comfort manner.关键词
