【摘要】：合肥市目前的城市用水都是来自淠史杭灌渠的供水,但随着城市经济的增长和交通体系网的形成,合肥市的人口在未来的几年内必将保持稳定的增长。2013年,为了满足和保证合肥市城市供水水源的需求,合肥市已经多次从淠史杭灌渠补水。可以预测在未来的几年内,原有的人工灌渠对城市供水可能无法满足城市人口日益增长的需要,因此就很有可能对原有的人工灌渠进行改造。 淠史杭灌渠建成使用过程中有多处干渠滑坡,通过在现场的勘察发现滑坡断土体多为膨胀土。膨胀土是一种性质极其复杂的问题土,本文以淠史杭灌渠淠河总干渠某处滑坡为工程背景,对膨胀土人工灌渠改造进行边坡稳定性分析研究。 本文基于有限元强度折减法的基本原理,运用Midas/GTS软件作为分析工具,以现场灌渠滑坡为工程背景,从宽度、深度两方面对灌渠改造,进行膨胀土人工灌渠改造的边坡稳定性分析研究。
[Abstract]:Hefei's current urban water supply comes from the Pishihang irrigation canal, but with the growth of the city's economy and the formation of a network of transport systems, the population of Hefei is bound to maintain a steady growth in the next few years. In 2013, In order to meet and guarantee the demand of water supply in Hefei city, Hefei has replenished water from Pishihang irrigation canal many times. It can be predicted that in the next few years, the original artificial irrigation canals may not be able to meet the increasing needs of the urban population for water supply, so it is very possible to reform the original artificial irrigation canals. During the construction and use of the Pishihang Irrigation Canal, there are many landslides in the main canal, and through the field investigation, it is found that the landslide fractured soil is mostly expansive soil. Expansive soil is an extremely complex problem soil. Based on the landslide of Pishihang Irrigation Canal, the slope stability of artificial irrigation canal is analyzed and studied in this paper. Based on the basic principle of the finite element strength reduction method, this paper uses Midas/GTS software as the analysis tool, takes the field irrigation canal landslide as the engineering background, and reconstructs the irrigation canal from two aspects of width and depth. The slope stability analysis of artificial irrigation canal reconstruction of expansive soil is carried out.
