山丘区小型水库输水管加固方案的分析与比选

Analysis and comparison of reinforcement schemes for the water pipelines of small reservoirs in mountain area

输水管作为小型水库的主要水工建筑物之一,其险情整治极为重要。受建筑物规模及投资额等多因素制约或影响,山丘区小型水库输水管安全评价及加固方案的选取有一定难度。在对咸宁市小型水库输水管加固经验总结的基础上,对输水管强度和抗裂是否满足规范要求的论证要点及输水管加固的主要选择方案进行了阐述,对类似工程的加固有一定借鉴意义。

As a main structure of small reservoir, the pipelines are of great importance. Limited by struc- ture size and investment, it is difficult to assess the safety of-pipelines and to choose reinforcement scheme. The paper summarizes the experience of pipeline reinforcement in Xianning City, Hubei Prov- ince. What＇s more, the main points in check of the strength and cracking resistance of the pipelines and the key issues in selection of reinforcement schemes are presented, for reference.
