B．建筑物、构筑物比较分散的场地
C．运输线路及地下管线较多、面积较大、地势平坦的地段
D．大部分屋面为内落水
E．道路低于建筑物标高，并利用路面雨水口排水的情况
参考答案：A, C, D, E
解析：
本题考核的是场地排水的形式。场地排水一般有以下两种形式。
（1）暗管排水。多用于建筑物、构筑物较集中的场地；运输线路及地下管线较多，面积较大、地势平坦的地段；大部分屋面为内落水；道路低于建筑物标高，并利用路面雨水口排水的情况。
（2）明沟排水。多用于建筑物、构筑物比较分散的场地，断面尺寸按汇水面积大小而定，明沟排水坡度为0.3%～0.5%，特殊困难地段可为0.1%。
熟悉场地排水形式的同时也要熟悉场地排水坡度，为了方便排水，场地最小坡度为0.3%，最大坡度不大于8%。
