摘要

比较了不同行业抗震设计规范中边坡地震影响系数和动态放大系数的取值方法，综述国内核电厂高边坡案例的研究进展。以某工程核安全级反倾层状软岩高陡边坡为例，探讨应用多种方法综合分析其在不同地震作用下的动态放大效应、支挡结构抗震性能和加固效果的分析思路。首先，基于典型二维计算剖面，采用拟静力法进行边坡的初步加固设计；然后，基于大型振动台试验和数值计算，研究了不同地震作用下软岩高边坡加速度动力放大效应、支挡结构的抗震性能；最后，通过现场工程监测评价边坡的加固效果。研究结果表明，在强震作用下，核安全边坡按其他行业规范中的抗震参数取值方法进行设计是可行的，通过振动台和数值分析验证边坡整体是稳定的，支挡结构抗震性能良好，该研究思路和方法是合理可行的，并能节约大量工程投资。研究成果可丰富核安全级软岩高陡边坡研究理论与方法，并为核安全级软岩高陡边坡抗震安全评价和工程设计提供技术支持。

Abstract

The methods of calculating seismic influence coefficient and dynamic magnification factor of seismic design code in different industries are compared

and the suitability of current nuclear safety guides to high slope anti-seismic stability assessment of nuclear safety grade is studied. Taking the typical anti dip layered soft rock high steep slope at a certain nuclear safety grade for example

this paper discusses the application of various methods to analyze the dynamic amplification effect

safety and seismic performance of retaining structures. Firstly

on the basis of typical two-dimensional calculation profile

the preliminary reinforcement design of slope is conducted by quasi-static method. Then

based on large-scale shaking table tests and numerical calculation

the dynamic amplification effect of the soft rock slope and the dynamic response characteristics of the retaining structure under different seismic loads are studied. Finally

the safety of the slope is evaluated by field engineering monitoring. The results show that under strong earthquake

it is feasible to design the nuclear safety slope according to the seismic parameters in other industry codes. The whole slope is stable and the seismic performance of the retaining structure is good by shaking table and numerical analysis. The research ideas and methods are reasonable and feasible

and a lot of engineering investment will be saved. The present research enriches the theory of high steep slope stability with nuclear safety grade and can provide technical support for seismic safety evaluation and engineering design of nuclear safety grade slopes.
