取竖向压力q=10kN/m2侧向压力q=10*0.333= 3.33kN/m2
设计值：
q=10* 1.4*1=14kN/m2
侧向压力q=14*0.333= 4.662kN/m2
1.1按裂缝控制计算配筋
1.1.1考虑地下水的作用
顶板覆土重顶板重等效竖向压力
顶板所受荷载：691.2+37.5+10=738.7kN/m2
土侧压力水侧压力侧向压力
侧墙上部所受荷载:109.1667+327.5+ 3.33=439.9967kN/m2
侧墙下部所受荷载：114.1667+342.5+ 3.33=459.9967kN/m2
顶板所受荷载侧墙重B+墙厚
底板所受荷载：738.7+206.25*2/ 6.5=802.2kN/m2。
