某工程公司低价中标了一矿区工业广场的改造工程，其中要在广场内修建一条l00m长的地下双孔钢筋混凝土排水暗渠。暗渠外断面尺寸为宽12m、高4．8m，渠底标高--5．8m，渠顶需覆土回填lm，并恢复广场绿化。暗渠东段50m的北面是一栋已建成的6层楼房，与暗渠净距5m。暗渠两侧无空地。该区域常年地下水位在一2．5m左右。
经批准的施工组织设计采用的施工方法为：暗渠西段采用双排钢板桩加横向支撑系统，双排轻型井点降水；东段50m采用双排水泥搅拌土重力式挡土墙兼挡水；机械挖土，土方外运。
项目实施前，项目经理为节省费用将水泥搅拌桩挡土墙改为悬臂式钢板桩，不设横向支撑，采用单排轻型井点降水；回填用的土方堆放在楼房北侧的狭长空地上，约需堆高5m。因工期紧迫，立即组织实施。
土方开挖至一3．5m时，发现钢板桩缝隙有渗水渗砂现象。挖N-4．5m时，楼房墙体出现裂缝。挖至～5．5m后，部分钢板桩倾覆，楼房墙体出现倾斜倾向，工程紧急停工。

1．分析钢板桩缝隙出现渗水渗砂的原因。 2．项目经理更改施工方案的做法有何不妥?说明正确做法。 3．在楼房北侧堆土的做法会造成哪些安全隐患? 4．工程紧急停工后，现场应如何进行应急处理?
