摘要
在研究污水管道维护费用函数的基础上,提出了城市污水管道维护优化决策模型,并运用该优化决策模型对四川岳池城东新区123段城市污水管道进行了维护优化决策。优化决策结果为:需采取维护措施的污水管道共19段,约占总管段数的15.44%,其中两段污水管道采取"更新"方案、两段污水管道采取"软管内衬"方案、15段污水管道采取"清淤"方案;其余104段污水管道无需采取维护措施而只例行检查。实例计算结果表明:应用城市污水管道维护优化决策模型得到的决策是有效的,可为污水管道的维护提供决策支持。
Based on the research on maintenance cost functions of sewers, a municipal sewer maintenance optimization decision model was established and used to perform the maintenance optimization decision of 123 sections of sewers at the New Eastern District of Yuechi County, Sichuan Province. There are 19 sections that need to be maintained, being about 15.44% of the total sections, among them 2 sections need to be replaced, 2 sections need to be lined with flexible liner, and 15 sections need to be dredged. The other 104 sections need not to be maintained. It is concluded that the decision made by municipal sewer maintenance optimization model is effective, and the model can provide decision support for sewer maintenance.
