本省兴建的小型水庫絕大部分都是采用土坝,土坝中常用的是心墙坝、均匀土質坝和土石混合织。因此在小型水庫建設中要貫彻多快好省的方針,合理的选择坝坡有极为重大的意义。 設計水庫拦水坝的坝坡,从經济和安全的原則出发,必需考虑以下几个問題: 1.根据不同基础土壤和坝身填料的抗剪强度进行坝坡稳定分析,使土坝在任何工作条件下(滿庫或泄空),損体不致发生局部或整体的滑动或坍塌,以保証工程安全。 2.在风浪冲击和暴雨浸蝕下,不致对坝体造成損害(如护坡石料移动,坝上坍塌)。 3.在一般情况下应使施工操作方便。
Most of the small reservoirs built in this province are earth dams. Heart dams, uniform earth dams and soil-rock mixed weaves are commonly used in earth dams. Therefore, in the construction of small reservoirs, we must implement the principle of “making our province more prosperous and more economical” and make rational choice of dam slopes with great significance. In designing the dam slope of a reservoir dam, economic and safety principles must be considered as follows: 1. Based on the shear strength of different base soil and dam filler, the slope stability analysis should be carried out to ensure that the dam will be under any working conditions Under (full or empty), the damage body will not occur partial or overall sliding or collapse, in order to ensure the safety of the project. 2. Under the impact of wind and waves and torrential rain erosion, will not cause damage to the dam (such as slope protection stone moving, dam collapsed). 3. Under normal circumstances should make construction and operation easy.
