Abstract

The present invention aims at the damage phenomenon that is easy to occur at the position of the conventional anchorage mode of the anti-seepage film around the upstream surface of the dam body or the flexible water-stop joints around the face plate at a certain depth below a certain depth after the water storage operation of the membrane or panel anti-seepage structure of the high rockfill dam, and discloses A mechanical dynamic tester and test method for a flexible anti-seepage joint structure that simulates the deformation and failure of different upper and lower contact materials on site. The mechanical dynamic test instrument group for flexible anti-seepage joint structure is mainly composed of pressure chamber and water inlet / outlet / air pipe valve system, mechanical power and sample installation platform system, displacement and pressure measurement feedback control system and monitoring system. Through the test, the failure mechanism of the anchorage joints around the anti-seepage membrane at a certain water depth can be revealed.

Description

technical field [0001] The invention relates to a mechanical dynamic test instrument for a joint structure of a flexible anti-seepage body and a test method thereof, and belongs to the technical field of membrane anti-seepage structures of high-membrane rockfill dams. Background technique [0002] Most of the reservoir dams in the development and utilization of water resources are built with earth-rock materials. Although most of them are medium and low dams, the highest dams in the world are earth-rock dams. The anti-seepage body in high rockfill dams mainly adopts cohesive soil core wall or reinforced concrete face plate, but when the foundation of the dam site is a deep covering layer, only clay core wall (or inclined core wall) can be used to connect the foundation concrete anti-seepage The type of wall. Rockfill dams with high clay core walls need to collect clay near the dam site, which not only costs a lot of land, but also causes damage to surface vegetation and aff...
