摘要

具有悠久历史的石结构是砌体结构的重要组成部分,本文作者经广泛调研和试验分析: ( 1 )提出以石粉为集料对石砌体进行抗震加固,寓环保与防灾于一体; (2)给出新型浆体配比和复合砂浆的强度等级,阐述加固技术和方法,建立灌浆石砌体抗震抗剪强度公式; (3)阐明抗震验算方法,提出基于模糊随机可靠理论的可靠性分析方法。
A study is made on masonry structure by combining with environmental protection and earthquake resistant for taking precautions against natural calamity. Based on wide investigations, the following results are obtained. Firstly, stone powder could be taken as an aggregate to make a new grouting material. Secondly, mix proportion of the material and strength grade of the composite mortar are given. The technology and method of the reinforcement are expounded. The earthquake-resistant and shear-resistant strength are also presented. Finally, the seismic check method and the reliability analysis method are put forward.
