问题 单项选择题

某悬臂式矩形水池,壁厚620mm,剖面如图所示。采用MU15烧结普通砖、M10水泥砂浆砌筑,砌体施工质量控制等级为B级。承载力验算时不计池壁自重,水压力按可变荷载考虑,假定其荷载分项系数取1.0。结构安全等级为二级。

若将该池壁承受水压的能力提高,下述何种措施最有效().

A.提高砌筑砂浆的强度等级

B.提高砌筑块体的强度等级

C.池壁采用MU10单排孔混凝土砌块、Mb10水泥砂浆对孔砌筑

D.池壁采用砖砌体和底部锚固的钢筋砂浆面层组成的组合砖砌体

答案

参考答案:D

解析:

解答如下:

根据上述两题的计算结果,可知,池壁承受水压的能力由池壁的竖向抗弯承载力控制,故采用D项措施可有效地提高池壁的抗弯承载力。
