特殊地形地质条件下的大型人工砂石系统设计与施工 --以小湾水电站孔雀沟人工砂石加工系统为例

小湾水电站孔雀沟人工砂石加工系统生产规模大，生产工艺复杂，对成品砂石料品质及成品仓储量调节能力要求高，但系统所处位置狭窄且地质条件复杂，施工干扰严重。因此系统总体布置设计按“多穿少切，车间平台适当外移，少扰动边坡，多走地下，充分利用空间”的原则进行。保证了系统顺利建成。

Design and construction of large-scale artificial aggregate system under special topogeological conditions

Artificial aggregate system in Kongquegou of Xiaowan Hydropower Station has a large production scale and complex production technique, which asks for high quality of finished aggregates or high storage regulation conditions, so the construction suffers from severe disturbance. Therefore, the layout of the system follows the principle of making use of underground spaces and moving the workshop outside by sustaining slopes, so that the system is successfully installed.
