摘　　要：涉核工程边坡指分布于抗震I类和II类建(构)筑物周围或附近地区的自然斜坡或人工边坡,其抗震安全性评价是核电厂或军工设施厂址各阶段安全性评价报告的主要内容之一。本文总结了国内外边坡抗震设计规范、核工程法规导则中关于边坡抗震验算的规定和现有涉核工程边坡的抗震设计经验,提出一套适合涉核工程边坡工程安全等级划分及设计安全标准确定、且包含对应不同核安全等级的边坡综合地震影响系数计算公式、静态分析及动态分析方法和抗震验算流程的指导思路。本文对中国核工业勘察设计协会编制团体标准《涉核工程边坡设计规范》(CNIDA2019-01)具有较好的借鉴意义。Nuclear-project-related slopes are natural or artificial slopes which locate around the structures or buildings classified as anti-seismic type I and type II referring to the Chinese code for seismic design of buildings.The seismic safety assessment of slopes involved in nuclear projects is one of the key components of the overall safety evaluation for the construction and operation of the nuclear power plants or military infrastructures.A review on seismic design codes for slopes of China and other countries,nuclear project regulations related to slope seismic inspection as well as current experiences on the design of nuclear-project-related slopes is presented.The procedures of slope seismic inspection based on static and dynamic analysis proposed in this paper could be suitable for the safety classification and design of nuclear-project-related slopes.A summary of the formulas evaluating comprehensive seismic coefficient is also provided.This study may be of significance for the development of association standard《Design Code for Nuclear-project-related slopes》of Nuclear Industry Exploration and Design(CNIDA).
