某岩溶地区治涝工程总布置设计

General Layout Design of Waterlogging Project in a Karst Area

某岩溶地貌地区处于低洼谷地,连年发生内涝灾害。通过对涝区地质、水文条件等综合分析,拟将涝区分为南、北两片,形成两个排涝通道。北片利用现状天然溶洞排涝,南片则新建排涝隧洞进行排涝。该设计将涝区洪水引至下游天然河道排走,较好地解决内涝问题,保障人民生活和财产安全。

A karst landform is located in low - lying valley and waterlogging disasters occur year after year. Through acomprehensive analysis of the geological and hydrological conditions in waterlogged areas it is proposed to divide thewaterlogging into two parts south and north to form two drainage channels. The northern slice uses the present natural karstcave to drain the waterlogging while south is a new drainage tunnel for drainage. The design will drain the flooded area intothe downstream natural river to better solve the waterlogging problem and ensure people＇ s life and property safety.
