摘要
该文以石家庄市石西500kv输变电工程为例,研究浅层地震反射波法在场地地震安评价中的应用条件、效果和范围。实例表明:浅层地震反射波法在场地稳定性和地震效应评价中起到了重要而不可替代的作用,对查明场地覆盖层厚度,配合钻探进行岩性划分,探测隐伏活动断层具有明显的作用。该文为今后在场地地震安评中勘察技术的选择提供了有意义的借鉴。
Taking Shixi 500kv power transmission and the application conditions, effect and scope of shallow ation of the site are studied. The case shows that： the transformation project in Shijiazhuang for an example, seismic reflection wave method in seismic safety evalu- shallow seismic reflection wave method plays an impor- tant and irreplaceable role in the evaluation of site stability and seismic effect. It has obviously investigation ef- fect for identification of the site overburden thickness, lithology determination combined with drilling tection of buried active faults. It provides significant reference for choice of investigation technique in safety evaluation of the site for future. and de- seismicsafety evaluation of the site for future.
