柳州市静兰防洪堤工程岩溶发育特征及渗漏评价

Characteristics of the karst and evaluation of the leakage of the flood control project of the Jinglan dike near Liuzhou

本文论述了柳州市静兰防洪堤工程区岩溶发育特征、规律,阐明了西江船厂区地下河系、溶洞、落水洞、漏斗、洼地等的发育规模、连通性,并进行岩溶渗漏评价。结果表明采取围井、填埋等措施后,渗漏量只有0 55×104m3 d,能有效地防止岩溶水的倒灌。

The article introduces the characteristics of karst in the Jinglan dike near the city of Liuzhou, describes the growth size and connectedness of underground rivers, solution caves, tundishes, sinkholes and depression zones near the Xijiang Boat Factory. Evaluation of the leakage of the flood control project has also been carried out. The results indicated that after such control measures as well-packing and landfilling have been taken, the leakage will occur at a rate of 5000 m^3/d and the flood hazard may be effectively controlled.
