摘　　要：针对中里坪拱坝实际工程情况,运用多拱梁法进行了应力计算和分析,以便掌握坝体在不同荷载组合工况的应力分布状况,为大坝可行性评价及蓄水过程提供理论依据。计算结果表明:(1)中里坪拱坝的主压应力在三种组合工况下均满足规范要求,拱坝结构有一定的安全裕度;(2)主拉应力也都在规范允许范围内。For the actual operation condition of Zhongliping Masonry Arch Dam,the stress calculation and analysis are made with the multi-arch beam method,so as to know the stress distributions under the operation conditions of various loading combinations,and then provides a theoretical basis for the feasibility evaluation on the dam body and the impoundment process.The calculation shows that not only the principal compressive stresses of Zhongliping Masonry Arch Dam under three loading combination conditions can all meet the specifications concerned with a certain safety allowance for the arch structure,but all the principal tensile stresses are also within the allowable area specified.
