摘要:
本文针对山区中小型河流洪水资料相对较少的情况,以地形数据DEM为基础,分析区域各典型频率洪水,计算淹没范围和淹没水深,并计算不同频率洪水淹没损失,以流域为单位绘制洪水淹没图,以试点县岫岩地区内河流为例,绘制各典型频率洪水淹没图,为洪灾损失评估和洪灾风险评价提供数据基础,为规划编制、监测预警提供信息支撑。

摘要:
The River Chenab is one of the main western rivers of the Indus River system in Pakistan, which undergoes intensive inundation almost every year during the late monsoon period. The present study performs flood frequency analyses for the river basin as well as simulates different levels of water flow in the system to speculate all kinds of inundation under different scenarios, i.e., to predict flood hazard and flood extended areas. Flood frequency analyses were performed at MARALA Headworks to Khanki Headworks. Data were collected from the Punjab Irrigation Department, Pakistan and from USGS and ASTER GDEM. The peak discharge of MARALA Headworks had been analyzed for 25 years. The preprocessing was performed in HEC Geo-RAS after preprocessing model run in HEC-RAS. After analysis the data were exported in HEC-RAS to ARCMAP to generate a floodplain and inundation map. Our analysis generated the result that different areas would be under water in different return periods. Flood hazards maps for different return periods 10, 20, 50 and 100 years were conducted using annual peaks flow of 35 years from 1980 to 2016. The maximum discharges at up and down stream for different periods were obtained using Gumbel distribution model results which showed that different areas were predicted under water in different return periods and affected areas after five years’ return period.

摘要:
Open channel junctions are encountered in urban water treatment plants, irrigation and drainage canals, and natural river systems. Junctions are very important in municipal sewerage systems and river engineering. Adequate theoretical description of flow through an open channel junction is difficult because numerous variables are to be considered. Equations of junction models are based on mass and momentum or mass and energy conservation. The objective of this study is to compare two junction models for subcritical flows. In channel branches, we solve numerically the Saint-Venant hyperbolic system by combining Preissmann scheme and double sweep method. We validate our results with HEC-RAS using Nash and Sutcliffe efficiency. In junction models, equality of water stage and complete energy conservation equation from HEC-RAS are compared. Outcome of the research clearly indicates that the complete conservation energy model is more suitable in flow through junction than equality of water stage model in serious situations.

摘要:
该文介绍了一项通过室内试验对HEC和水泥稳定渣土的抗压强度、回弹模量、干缩性能、温缩性能等进行的试验分析.对比分析了HEC与水泥两种固结剂稳定渣土的效果,HEC固结渣土强度、刚度高,温缩、干缩变形小,整体性能要优于水泥.对此,可以采用固结剂HEC来稳定渣土.
