Description
Technical field
The invention belongs to water power hydraulic engineering hydraulic structure technical field, be specifically related to a kind of mixed dam.
Background technology
Along with water power implementation, in the abundant southwest of hydraulic power potentials, the Northwest, large quantities of high dams are built, building
Or it is yet to be built.Earth and rockfill dam is modal a kind of dam type in current Dam constructions, is also a kind of dam type with fastest developing speed, accounts for built
More than the 95% of dam sum.The height of dam earth and rockfill dam more than 15m in the whole world has more than 29000, and wherein China has more than 15000 seats,
Mainly include homogeneous earth dam, core wall dam and CFRD etc..
Reinforced concrete face rockfill dam is a kind of new dam type starting in the later stage seventies in last century to grow up, and it is in reality
The feature that safety, economy, easy construction and adaptability are good is embodied, although start late but develop quickly, deeply in trampling
Favored by Ba Gongjie.By in JIUYUE, 2011, the most built, at the rock built and plan to build, from engineering quantity, dam
Height is all occupied the forefront to project scale.China is the most built and has more than 270 building rock, and sum accounts for global 50%.
Along with accumulation and the raising of design level of Dam Construction experience, the height of rock is also constantly increasing, water cloth
A strip of land between hills dam is up to 233m, for the most built high CFRD, also becomes the successful case of 250m level high CFRD.
The 250 300m level superelevation rocks that great Shi gorge, thatch Ha Xia etc. plan to build are currently also in the middle of project study.
The safety issue of dam work bound pair superelevation rock, is primarily present following worry: (1) can not correctly predicted surpass
Panel deformation, stress and the requirement to sealing material that high face dam dam settlement and sedimentation cause.(2) existing experiment hands
Duan Caiyong material for scale model, if can correctly predicted superelevation face dam dam permeation stability problem and the thing of dam material
Reason mechanical property.(3) due to the existence of above-mentioned uncertain factor, if high anti-extrusion, the concrete slab of high cracking resistance can be proposed
Material and version；Whether can propose to meet joint water stop structure form and the material of superelevation face dam large deformation.
If deformation, panel deflection and the stress of 300m level superelevation rock planned to build, the deflection of joint seal
Level reaches the degree of 200m level rock, can also accept for Ba Gongjie, the most just solve 300m level superelevation panel enrockment
The technical bottleneck on dam.
Summary of the invention
It is an object of the invention to overcome the technical barrier of 300m level superelevation rock in prior art, give full play to steel
