- 摘要:
- 構(gòu)建山地丘陵城市排水管網(wǎng)模型時(shí)，山嶺大面積的雨水匯水區(qū)成為研究者必須考慮的問題。針對(duì)山嶺匯水特點(diǎn)和非線性水庫(kù)匯流模型的缺陷，提出基于等流時(shí)線的山嶺匯水區(qū)劃分方法，將山嶺雨水通過虛擬節(jié)點(diǎn)和管段排入管網(wǎng)系統(tǒng)。以Z市某轄區(qū)排水管網(wǎng)的InfoWorks ICM模擬過程為例，研究了基于等流時(shí)線的匯水區(qū)劃分方法和常規(guī)泰森多邊形匯水區(qū)劃分方法對(duì)模擬結(jié)果的影響。結(jié)果表明，采用基于等流時(shí)線的山嶺匯水區(qū)劃分方法時(shí)，模擬結(jié)果與山嶺地區(qū)雨水匯流過程更為吻合，對(duì)該類區(qū)域排水管網(wǎng)的排水能力評(píng)估和內(nèi)澇模擬具有一定的借鑒意義。
- Abstract:
- When establishing drainage pipe network model in a mountainous and hilly city, researchers must take into account the problem of large rainwater catchments in the mountainous areas. Aiming at the characteristics of stormwater confluence in the mountain and the defects of non-linear reservoir conflux model, a catchment division method for the mountain based on isochrones was proposed, and stormwater in the mountain was discharged into the pipe network system through virtual nodes and pipes. An example of a drainage system in a district of Z city simulated by InfoWorks ICM software was given, and the effect of catchment division methods based on isochrones and conventional Thiessen polygon on the simulation results were explored. The simulation results were more consistent with the stormwater conflux process in the mountain area when the method based on isochrones was adopted, which had certain reference significance for the drainage capacity evaluation and urban flooding simulation of drainage pipe network in similar regions.
