Parameter set of earth and rockfill dam longitudinal reinforcement and design method of earth and rockfill dam longitudinal reinforcement

Abstract

The invention discloses a parameter set of a longitudinal reinforcement of an earth and rockfill dam and a design method of the longitudinal reinforcement of the earth and rockfill dam. The design method of the longitudinal reinforcement of the earth and rockfill dam comprises the following steps: determining design parameters of the longitudinal reinforcement of the earth and rockfill dam; calculating the deformation resistance of the longitudinal reinforcement of the earth and rockfill dam; analyzing the stress of the longitudinal reinforcement of the earth and rockfill dam; carrying out hydraulic analysis when the longitudinal reinforcement of the earth and rockfill dam is overtopped by the flood; re-checking the strength of the longitudinal reinforcement of the earth and rockfill dam after being scoured; the longitudinal reinforcement of the earth and rockfill dam has the advantages of seepage prevention, stress resistance, deformation resistance and overtopping without collapse; the engineering investment can be effectively saved by 30-20%, and the economic benefit is obvious; and the conventional earth and rockfill dam is reinforced, so that the safety operation risk of a dangerous reservoir is greatly solved, the congenital defect that the earth and rockfill dam is easy to break is overcome, and the safe operation of the reservoir is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a parameter set of a longitudinal reinforcement of an earth-rock dam and a design method for a longitudinal reinforcement of an earth-rock dam based on the parameter set of the longitudinal reinforcement of an earth-rock dam. Background technique [0002] So far, earth-rock dams are still the first choice for all kinds of dam construction. At present, earth-rock dams account for about 78% of all other dam types in the world, and the proportion in developing countries is even higher. [0003] According to statistics, as of 2019, there are more than 98,900 dams in China, of which more than 98% are small and medium-sized dams, and earth-rock dams are the most common. Taking Sichuan as an example, there were 7,878 small and medium-sized dams in Sichuan Province according to statistics from 2013 to 2014, of which 7,186 earth-rock dams accounted for 91...
