新郑国际机场二期工程东西贯穿道路基坑施工监测研究

Study on Construction Monitoring of Foundation Pit for the Road Running from East to West of Xinzheng International Airport Phase Ⅱ

以新郑国际机场二期工程东西贯穿道路基坑施工为依托,采用工程监测的方法,对基坑工程的水平位移、竖向位移、水位监测结果进行分析。结果表明:在不同基坑支护方案下,基坑的水平位移、竖直位移以及地下水位均有相应变化,但都未达到警戒值。施工方案合理可靠,满足安全施工条件,保证了施工安全。

Taking excavation engineering of the east-west road （ phase II） in Xinzheng International Airport as the background, the paper by means of engineering monitoring analyzed the horizontal and vertical displacement of the foundation pit, as well as the water level observations thereof. The results show that, in relation to different retaining schemes, the horizontal and vertical displacement of foundation pit and the underground water level, are subject to change accordingly, but do not reach the warning value. The construction scheme, which is reasonable and reliable, meet the security requirement and ensure the safety.
