Partition structure of gravelly soil core wall dam
The invention discloses a partition structure of a gravelly soil core wall dam. The partition structure is sequentially divided into an upstream protection slope, an upstream hard rock enrockment area, an upstream transition area, an upstream filter material area, a gravelly soil core wall, a downstream filter material area, a downstream transition area, a downstream hard rock enrockment area, a downstream soft rock enrockment area, a downstream protection slope and a drainage layer from upstream to downstream, an upstream soft rock enrockment area is further arranged between the upstream hard rock enrockment area and the upstream transition area, the upstream hard rock enrockment area and the downstream hard rock enrockmentl area are made of hard rocks with the strength larger than 30 MPa, and the upstream soft rock enrockment area and the downstream soft rock enrockment area are made of soft rocks with the strength smaller than 30 MPa. According to the partition structure, more soft rocks mined in a stock ground can be utilized during dam filling, the waste slag amount is reduced, the project investment is reduced, and meanwhile the problem that a gravelly soil core wall dam is built in an area lacking of hard rocks but with more soft rocks can be solved.
本发明公开了一种砾石土心墙坝的分区结构，包括从上游至下游依次分为上游护坡、上游硬岩堆石区、上游过渡区、上游反滤料区、砾石土心墙、下游反滤料区、下游过渡区、下游硬岩堆石区、下游软岩堆石区、下游护坡和排水层，在上游硬岩堆石区和上游过渡区之间还设置有上游软岩堆石区，上游硬岩堆石区和下游硬岩堆石区采用强度大于30MPa堆筑的硬质岩，上游软岩堆石区和下游软岩堆石区采用强度小于30MPa堆筑的软质岩。本发明可在大坝填筑时更多利用料场开采的软质岩，减少弃渣量，降低工程投资，同时可解决缺少硬质岩而软质岩较多的地区修建砾石土心墙坝的问题。
