题目内容
[案例二] 背景 某高速公路第五施工合同段地处城郊，主要工程为路基填筑施工。其中K48+010～K48+328段原为路基土方填筑，因当地经济发展和交通规划需要，经各方协商，决定将该段路基填筑变更为(5×20+3×36+5×20)m预应力钢筋混凝土箱梁桥，箱梁混凝土强度等级为C40。变更批复后，承包人组织施工，上部结构采用满堂式钢管支架现浇施工，泵送混凝土。支架施工时，对预拱度设置考虑了以下因素：(1)卸架后上部构造本身及活载一半所产生的竖向挠度。(2)支架在荷载作用下的弹性压缩挠度。(3)支架在荷载作用下的非弹性压缩挠度。(4)由混凝土收缩及温度变化而引起的挠度。根据设计要求，承包人对支架采取了预压处理，然后立模、普通钢筋制作、箱梁混凝土浇筑、采用气割进行预应力筋下料；箱梁采用洒水覆盖养生；箱梁混凝土强度达到规定要求后，进行孔道清理、预应力张拉压浆，当灰浆从预应力孔道另一端流出后立即终止。箱梁现浇施工正值夏季高温，为避免箱梁出现构造裂缝，保证箱梁质量，施工单位提出了以下三条措施：(1)选用优质的水泥和集料。(2)合理设计混凝土配合比，水灰比不宜过大。(3)严格控制混凝土搅拌时间和振捣时间。 问题： 除背景资料中提到的三条构造裂缝防治措施外，再列举两条防治措施。

[案例一] 背景 某高速公路M合同段，路面采用沥青混凝土，路线长19.2km。该路段地处平原地区，路基横断面以填方3～6m高的路堤为主，借方量大，借方的含石量40%～60%。地表层以黏土为主，其中K7+200～K9+800段，地表层土厚7～8m，土的天然含水量为40%～52%，地表无常年积水，孔隙比为1.2～1.32，属典型的软土地基。结合实际情况，经过设计、监理、施工三方论证，决定采用砂井进行软基处理，其施工工艺包括加料压密、桩管沉入、机具定位、拔管、整平原地面等。完工后，经实践证明效果良好。 在施工过程中，针对土石填筑工程，项目部根据作业内容选择了推土机、铲运机、羊足碾、布耠．机、压路机、洒水车、平地机和自卸汽车以及滑模摊铺机等机械设备。在铺筑沥青混凝土路面面层时，因沥青混凝土摊铺机操作失误致使一工人受伤，并造成设备故障。事故发生后，项目部将受伤工人送医院治疗，并组织人员对设备进行了抢修，使当天铺筑工作顺利完成。 问题： 本项目若采用抛石挤淤的方法处理软基是否合理请说明理由。
