清河泵站设计装机流量150m3/s，出口防洪闸所处堤防为1级。招标人对出口防洪闸工程施工标进行公开招标。有关招标工作计划如下：5月31日提交招标备案报告，6月1日发布招标公告，6月11日～15日出售招标文件，6月16日组织现场踏勘，6月17日组织投标预备会，7月5日开标，7月6日～10日评标定标。招标工作完成后，A单位中标，与发包人签订了施工承包合同。工程实施中发生如下事件：
事件1：Ⅰ-Ⅰ段挡土墙（示意图如下图所示）开挖设计边坡1：1，由于不可避免的超挖，实际开挖边坡为1：1.15。A单位申报的结算工程为50m×（S1+S2+S3），监理单位不同意。
事件2：原定料场土料含水量不能满足要求，监理单位指示A单位改变了挡土墙墙后填土料场，运距由1km增加到1.5km，填筑单价直接费相应增加2元/m3，A单位提出费用变更申请。
Ⅰ-Ⅰ段挡土墙土方开挖工程计量中，不可避免的施工超挖产生的工程量能否申报结算？为什么？计算Ⅰ-Ⅰ段挡土墙土方开挖工程结算工程量
