In this paper,based on LiYao test section of Beijing-Shanghai high-speed rail project,make a study on field test technology of CFG pile composite foundation in deep soft soil of high speed rail.Test results and study show that:joint test method of single point settlement equipment-liquid level settlement equipment which advanced originally in this subject is highly applicable to deep settlement observation for deep soft soil,but the disadvantage is higher cost;at the permitting of cost,it is to recommend the use of liquid level settlement method,and supplemented by settlement plate or section settlement pipe,will be able to obtain better test results for embankment or shallow foundation settlement test;this subject adopts advanced remote automatic monitoring system,and the data processing is computerized by database software developed by Southwest Jiaotong University.The automatic monitoring system and software applications have been successful and effective.
