摘要
云南万家口子水电站为坝高157.60 m的碾压混凝土拱坝,混凝土月浇筑强度高,所需石料较多。为此,结合石料场的工程地质条件,进行合理的开采规划,针对开采形成的永久高边坡,采取相应的支护措施,从而确保高边坡的稳定及石料供应强度。
Wanjiakouzi Hydropower Station located in Yunan Province is designed with a RCC arch dam with total dam height of 157.6m. High monthly concreting intensity requires much rock materials. Proper rock quarrying plan- ning was conducted according to engineering geological conditions. Corresponding supports were constructed for the permanent high slope formed due to quarrying, so as to ensure high slope stability and rock material supply.
