题型:单项选择题

某沟槽长335.1m,底宽为3m;室外地坪设计标高为-0.3m,槽底标高为-0.3m,无地下水,放坡系数为1:0.67,沟槽两端不放坡,采用挖斗容量为0.5m3的反铲挖掘机挖土,载重量为5t的自卸汽车将开挖土方量的60%运走,运距为3km,其余土方量就地堆放。经现场测试的有关数据如下:
(1)假设土的松散系数为1.2,松散状态容重为1.65 t/m3
(2)假设挖掘机的铲斗充盈系数为1.0,每循环1次时间为2分钟,机械时间利用系数为0.85;
(3)自卸汽车每一次装卸往返需24分钟,时间利用系数为0.80。
注:“时间利用系数”仅限于计算台班产量时使用。

挖掘机台班产量为( )m3/台班。
