摘　　要：以滨海电站工程深基坑为背景,针对项目临近电厂运行区、狭窄空间场地及强透水、软弱地层条件,采用灌注桩、高压旋喷土锚、混凝土支撑等多种工艺相结合的基坑围护技术,在复杂场地条件深基坑中得到了有效应用。Taking the deep foundation pit of the Binhai Power Station project as the background,it adopted a combination of cast-in-place piles,high-pressure rotary grouting soil anchors,concrete supports and other technologies for the project’s proximity to the power plant operating area,narrow space sites,and strong permeable and weak stratum conditions.Foundation pit enclosure technology had been effectively applied in complex site conditions in deep foundation pits.
