基于观音阁水库输水工程料场储量估算及质量

Material Pit Reserves Estimation and Quality Analysis for Delivery Project of Guangyinge Reservoir

据对天然建筑材料场地的勘察,确定混凝土骨料场3个,距主洞及各支洞间交通条件较好,满足施工用料运输要求。其中1~#迎水寺骨料场距各供应区6-15km,2~#牛心台骨料场距各供应区13-25km,3~#桥头骨料场距各供应区0.5-20km。各骨料场混合砂砾料勘察总储量436.9万m^3;净砂总储量203.84万m^3,净砾石总储量355.03万m^3,有一定比例的弃料。各骨料场细骨料除含泥量偏大(即含有一定量的泥块)外,其它各项评价指标均合格。

According to the investigation for natural construction material pit,3 concrete aggregate fields were picked up. It is convenient of the traffic conditions between the main hole and each drift,which meets the requirement of construction materials transportation. Of which,there are 6-15 km from 1^# Yingshui Temple aggregate filed to each supply area,13-25 km of 2# Niuxintai aggregate field and0. 5-20 km of 3^# Qiaotou aggregate material field. Gross reserves of mixed sandy gravel material investigated is 4. 369 million m^3,2. 0384 million tons of net sand,3. 5503 million m^3 of gross reserves of net sandy rock,and there was a certain proportion of derelict. The silt content（ containing a certain amount of mud） in fine aggregate is rather large in each material pit,except this,all other evaluation indexes are qualified.
