判断题 案例分析题

【背景资料】某5层砖混结构宿舍楼，7度抗震设防。墙厚240mm，墙长48m，宽12m，实际地质情况为西部地基土为中偏高压缩性土，而东部较坚硬。因紧邻该建筑的东侧建有同类型的房屋，并具有详细的地质勘察资料，故建设方省去了地质勘察，要求设计院按该地质勘察资料确定地基承载力。在房屋报建时因无地质资料，未获审批，后不得不补做了勘察，但此时基础已施工完成。施工方为了赶工期，新招进一劳务作业队伍进行墙体砌筑，发现砌筑砂浆层饱满度为75%，皮数砖同缝，多处转角和纵横墙丁字相交处的施工临时洞口处留直槎等情况，当房屋建至5层，墙面开始出现少量细微裂纹，随后逐步发展为裂缝，且不断增多。

请根据上述背景资料完成以下选项。

西部地基土为中偏高压缩性土，而东部较坚硬，地基不均匀沉降是其主要原因。
