新疆小山口水电站工程坝基岩石特性分析与工程措施研究

Rock Characteristics of Dam Foundation and the Engineering Measurements of Xiaoshankou Hydropower Station in Xinjiang

通过对新疆小山口水电站工程坝基岩石的特性分析和试验研究,确定在泥岩基础的混凝土固结灌浆之前首先应该进行接触灌浆,使混凝土与泥岩基础之间的软弱接触面形成整体,从而保证固结灌浆的效果;通过对混凝土与泥岩之间饱和抗剪试验研究,最终确定加基础面锚筋或者锚墩桩,以确保水工建筑物在工作状态下的抗滑稳定性。

Based on rock characteristics of Xiaoshankou Hydropower Station Project in Xinjiang,this paper determines that contact grouting should be conducted before consolidation grouting,making the contact surface between mudstone and concrete forming a whole to ensure the effects of consolidation grouting.Through the saturated shear resistant experiments and research,This paper validates that the anchor rods or anchor piers should be increased in order to ensure the skid resistance stability of the hydraulic structures under operation conditions.
