摘　　要：金河电站调压室交通洞、压力管道以及地面发电厂房等部位由于岩石破碎等原因,为满足施工、设计要求,在隧洞超前支护,径向支护及边坡处理等整治工程中中空注浆锚杆应用较多,均能很好地改良围岩,达到理想的支护效果.During construction of the Jinhe Hydropower Station, crushed rock conditions were encountered in surrounding struts areas of the access tunnel of surge shaft, pressure penstock and surface powerhouse. To meet the needs of design and construction , a wide variety of hollow grouted anchor bars was used to support and protect these strata of rock, as well as to make radial reinforcement and slope stabilization. This measure significantly improved the performance of the surrounding rocks and had demonstrate muc...
