       Mr. Shute teaches us maths in a middle school this term. He works hard and is friendly to us all. So

we like to listen to his lectures(讲课)and love the old man.

       But sometimes Mr. Shute forgets something when he's thinking over some problems. For example,

he wears his wife's hat or gets on a wrong bus. We all know him well and nobody laughs at him.

       One afternoon it was very hot while Mr. Shute was thinking over a problem in his room. He forgot to

turn on the electric fan(电扇)and several hours later he was all wet through. His wife came back and found it. She asked him to have a bath(洗澡). He thought she was right and went to the bath room. He didn't

stop thinking while he was lying in the bathtub. Suddenly he found he forgot to take off his clothes. He

hurried to jump out of it and looked at them carefully. At last he found they were dry and then said to

himself,"Luckily I haven't poured(注)any water into the bathtub! "

某铜冶炼厂，拟依托自有矿山实际生产能力实施冶炼厂扩建工程，扩建规模为年产15万t铜，采用诺兰达熔炼生产工艺。该冶炼厂现有工程采用火法冶炼，单转单吸制酸，制酸尾气SO₂有超标现象；设有全厂污水处理站，生产废水和生活污水混合后进行处理，总砷、总铜、总铅、总锌、总镉可做到达标排放。在厂区附近设有固体废物填埋场，防渗系数1×10^-6cm/s，防渗层为3m厚黏土。已知废水排放量2000m³/s，岸边连续排放，总铅1mg/L，河流本底0.01mg/L，流量为0.02 m³/s。该冶炼厂周围分布有村庄和农田。

根据以上内容，回答以下问题。

某公路钢筋混凝土简支梁桥，其计算跨径L=14.5m，设计荷载为公路—Ⅱ级荷载。主梁由多片T形梁组成，其中单片主梁断面尺寸如下图所示，采用混凝土标号25，R_a=14.5MPa，主筋为Ⅱ级钢筋，R_g=340MPa。试依据《公路桥涵设计通用规范》(JTG D60—2004)、《公路钢筋混凝土及预应力混凝土桥涵设计规范》(JTG D62—2D04)进行设计计算。

假定不计受压钢筋面积，h_o=67.5cm，并假定计算跨中弯矩，M_恒=631.4kN·m，M_活=289.3kN·m。试确定按承载能力极限状态计算出的跨中截面钢筋面积与（）项数值最为接近。

A．64.62cm²

B．53.23cm²

C．47.47cm²

D．71.88cm²
