双锚固充水式橡胶坝理论分析及简化设计方法
Theoretical analysis and simplified design method of double-anchored water-inflated rubber dam
摘要
Abstract
Rubber dams are widely employed for urban river and canal impoundment.They are the preferred water-retaining structures in water supply projects of small and medium-sized cities.Previous studies have predominantly concentrated on the stress and deformation characteristics of single-anchored dams,employing tabular methods to design geometric dimensions and tensile forces.Double-anchored lines are more commonly used in practical engineering.However,the engineering design method is not perfect.This study establishes a fluid-structure interaction theoretical model for these dams,the accuracy of the theoretical model is verified by model tests.The effects of anchor line distances,perimeters,and internal water heads on the cross-sectional shape and tension force are analyzed.Results indicate that increasing internal water head causes the ultimate external water level,cross-sectional area,and tension force to increase nonlinearly,while the dam width decreases nonlinearly.Increasing the perimeter results in nonlinear increases in ultimate external water level,dam width,cross-sectional area,with minimal impact on tension force.A simplified design equation is derived by fitting the geometric dimensions and tensile forces under design conditions using a dual-exponential growth curve model.关键词
