Portion's region overlay is equipped with the fully wrapped around First Transition bed of material in the outer surface of the first soft rock reclamation district；
The heap rock layers that agglomerated regions stablize support can be separated by the first soft rock reclamation district by being equipped in the first soft rock reclamation district
Separation structure；
In core-wall downstream, side bottom is equipped with the anti-filter bed of material, the second soft rock reclamation district is equipped with from bottom to top from the anti-filter bed of material, second
The second transition bed of material is equipped between soft rock reclamation district upstream side and core-wall downstream side；
The upstream side of the First Transition bed of material is equipped with upstream slope-protection, and downstream protection slope is equipped in the second soft rock reclamation district downstream side；
It further include the drainage system for being set to core-wall downstream.
Said program by the First Transition bed of material and heap rock layers separation structure to the first soft rock reclamation district of core-wall upstream into
Row support protection, soft rock is fully wrapped around, reduce dam body occur seepage failure possibility, it is ensured that dam body it is safe and reliable
Property, make it possible using local soft rock build a dam.
Specifically, the enrockment separation structure include against the first soft rock reclamation district downstream side be arranged from bottom to top with
It is the second contour heap rock layers of first soft rock reclamation district, horizontally disposed at least one layer of by the first soft rock in the first soft rock reclamation district
Reclamation district is separated into the third heap rock layers in polylith region；
The First Transition bed of material be set to the first soft rock reclamation district upstream side, top and the second heap rock layers and core-wall it
Between；
The third heap rock layers upstream side is abutted with the First Transition bed of material positioned at the first soft rock reclamation district upstream side, third enrockment
Layer downstream side is abutted with the second heap rock layers.
Further, in the upper of the upper surface of the first heap rock layers, the upper and lower surface of third heap rock layers and the second heap rock layers
Trip side is equipped with geotextiles.
Preferably, first soft rock reclamation district and the second soft rock reclamation district are filled using soft rock and hard rock blending.
Specifically, the drainage system includes the funnel-shaped row between the second soft rock reclamation district and the second transition bed of material
Water band and the horizontal drainage band for being set to core-wall downstream and being connected to funnel-shaped drainage belt bottom；
It is equipped with geotextiles in the intersection of funnel-shaped drainage belt, horizontal drainage band and the second soft rock reclamation district.
Preferably, the upstream slope-protection is concrete precast block bank protection or pitched work.
Preferably, the downstream protection slope is dry stone pitching or grassed slope.
The present invention remarkable result be：
1. utilizing soft-rock damming to greatest extent, rejected material, waste are reduced, the destruction to environment is reduced.
2. excavated material and local materials can be efficiently used, solves engineering cubic metre of earth and stone equilibrium problem, reduces construction investment,
Obvious economic.
