广深准高速铁路既有线基床加固补强技术研究

STUDY ON TECHNIQUE OF CONSOLIDATING AND REINFORCING THE EXISTING ROAD BED FOR GUANGSHEN QUASIHIGH-SPEED RAILWAY

广深准高速铁路有部分区段利用既有路基，根据技术要求，需加固补强。广深铁路运输十分繁忙，要在确保正常行车条件下进行基床加固，技术难度很大，如果限速运行或封锁线路，又会造成巨大的经济损失。本文系统全面地论述了为解决这些问题进行的试验研究和应用效果。

According to the technical demands, some sections of the existing road .bed in Guang-shen quasi-high--speed railway should be consolidated and reinforced. Guang-shen railway is very busy. So it is difficult in technique to reinforce the road bed under the regular driving. If liciting speed or closing the railway,it must cause a great economic loss. This report expounds the experimental study all-sidedly on how to solve these problems and its application effect.
