Which of the following will most likely resolve the problem？（） Run cfgdev on the VIO server and re-run the mkvdev command.。 Run chdev -a sea_enable=yes on the physical Ethernet adapter.。 Remove and re-add the virtual Ethernet adapter.。 Remove the IP address from the physical adapter and re-run the mkvdev command.。
某新建工程，建筑面积82000m2，地下3层，地上20层，钢筋混凝土框架一剪力墙结构，距邻近6层住宅楼7m。地基土层为粉质黏土和粉细砂，地下水为潜水，地下水位一9.5m，自然地面一0.5m。基础为筏板基础，埋深14.5m，基础底板混凝土厚1500mm，水泥采用普通硅酸盐水泥，采取整体连续分层浇筑方式施工。基坑支护工程委托有资质的专业单位施工，降排的地下水用于现场机具、设备清洗。主体结构选择有相应资质的A劳务公司作为劳务分包，并签订了劳务分包合同。 合同履行过程中，发生了下列事件：
事件1：基坑支护工程专业施工单位提出了基坑支护降水采用“排桩+锚杆+降水井”方案，施工总承包单位要求基坑支护降水方案进行比选后确定。
事件2：底板混凝土施工中，混凝土浇筑从高处开始，沿短边方向自一端向另一端进行，在混凝土浇筑完12h内对混凝土表面进行保温保湿养护，养护持续7日。养护至72h时，测温显示混凝土内部温度70℃，混凝土表面温度35℃。
事件3：结构施工到十层时，工期严重滞后。为保证工期，A劳务公司将部分工程分包给了另一家有相应资质的B劳务公司，B劳务公司进场工人100人。因场地狭小，B劳务公司将工人安排在本工程地下室居住。工人上岗前，项目部安全员向施工作业班组进行了安全技术交底，双方签字确认。
事件1中，适用于本工程的基坑支护降水方案还有哪些？
