摘　　要：以郑州市第七人民医院生活配套区为背景,依据河南地矿集团工程物探地质资料,运用FLAc3D建立了地基开挖模型,对喷射混凝土支护进行了研究.实施分步开挖,建立了地基开挖进度和土体沉降间关系.为地基开挖引起地表沉降以及地基自身的稳定性分析打下基础,为采用更有效的工程措施控制地表沉降提供了理论依据.This paper is based on living district of Zhengzhou Seventh Hospital. According to geological data provided by Henan Geology and Mineral Resources Engineering Group, three dimension numerical modal of foundation excavation is established based on FLAC3D. To study soil settlement with excavation more exactly. Shotcrete are studied. The relationship between soil settlement and excavation process is established. The result also provides theoretical foundation for soil settlement problem caused by foundation excavation and its control.
