一、原理本诺谟图编制的目的,是供圆形压力隧洞衬砌初步设计时,初步选择衬砌型式和衬砌尺寸之用。衬砌型式,采用了混凝土衬砌、钢筋混凝土衬砌,混凝土衬砌加钢筋水泥喷浆层、混凝土衬砌加钢板衬砌等四种。诺谟图的编制,根据1972年颁发的苏联《水工隧洞设计指示》进行,按极限状态方法进行计算。
First, the principle Benmo map preparation purpose is for the initial design of circular pressure tunnel lining, the initial choice of lining type and lining size. Lining type, using a concrete lining, reinforced concrete lining, concrete lining with reinforced cement grouting layer, concrete lining with steel lining and other four. The preparation of the nomogram is based on the Soviet Union’s “Design Guidelines for Hydraulic Tunnels” issued in 1972 and calculated according to the limit state method.

摘要：国库集中支付制度实施背景我国长期以来实行“分散支付”的国库管理制度、财政性资金缴库和拨付，主要通过征收机关和预算单位设立多重账户分散进行。由于各级财政、税务、海关及其他政府收费部门都自行设有众多的收入过渡账户，因此，大多数单位都要通过上述过渡账户收付资金。这样做的最大弊端是上级单位通过收入过渡截流财政资金，另外，主管部门不及时将资金缴入国库，大量预算外资金沉淀在各部门账户上。在目前深化财务管
