简述使用tkinter模块创建一个图形用户界面应用程序的主要步骤。
承包单位提请施工组织设计(施工方案)报审时,应满足哪些条件?
某城市引水工程,输水管道为长980m、DN3500mm钢管,采用顶管法施工;工作井尺寸为18m×20m,挖深15m,围护结构为φ800mm钻孔灌注桩,设四道支撑。工作井挖土前,经检测发现三根钻孔灌注桩桩身强度偏低,造成围护结构达不到设计要求。调查结果表明混凝土的粗、细骨料合格。顶管施工前,项目部把原施工组织设计确定的顶管分节长度由6.6m改为8.8m,仍采用原龙门吊下管方案,并准备在现场予以实施。监理工程师认为此做法违反有关规定并存在安全隐患,予以制止。顶管正常顶进过程中,随顶程增加,总顶力持续增加,在顶程达三分之一时,总顶力接近后背设计允许最大荷载。
问题
1.钻孔灌注桩桩身强度偏低的原因可能有哪些?应如何补救?
2.说明项目部变更施工方案的正确做法。
3.改变管节长度后,应对原龙门吊下管方案中哪些安全隐患点进行安全验算?
4.顶力随顶程持续增加的原因是什么?应采取哪些措施处理?

某公司中标承建中压A燃气管线工程,管道直径DN30mm,长26km,合同价3600万元。管道沟槽开挖过程中,遇到地质勘查时未探明的废弃砖沟,经现场监理工程口头同意,施工项目部组织人员、机具及时清除了砖沟,进行换填级配砂石处理,使工程增加了合同外的工作量。项目部就此向发包方提出计量支付,遭到计量工程师拒绝。监理工程师在工程检查中发现:(1)现场正在焊接作业的两名焊工是公司临时增援人员,均已在公司总部从事管理岗位半年以上;(2)管道准备连接施焊的数个坡口处有油渍等杂物。检查后向项目部发出整改通知。
问题
1.项目部处理废弃砖沟在程序上是否妥当?如不妥当,写出正确的程序。
2.简述计量工程师拒绝此项计量支付的理由。
3.两名新增焊接人员是否符合上岗条件?为什么?
4.管道连接施焊的坡口处应如何处理方能符合有关规范的要求?
