“七五”期间,我国公路建设取得了很大成就。五年新建公路8万多公里,总里程突破百万公里;高速公路实现了从无到有,建成以沈大公路为代表的高速公路522km;新建二级以上高等级公路2.4万多公里;新、改建桥梁2.5万座,开创了公路建设的新局面。同时,公路建设中也还有一些问题尚需分析研究,工程投资严重超概算就是主要问题之一,本文拟就这个问题做些探讨。一、公路工程投资超概算的原因分析当前,公路工程实际投资超过概算是较普 During the “Seventh Five-Year” period, great achievements have been made in highway construction in our country. Over the past five years, more than 80,000 kilometers of new highways have been built and the total mileage has exceeded one million kilometers. The expressway has achieved 522km of expressways represented by Shen-Da Highway from scratch and more than 24,000 kilometers of new high-grade highways , 25,000 bridges were reconstructed, creating a new situation in highway construction. At the same time, there are still some problems in highway construction that need to be analyzed and studied. One of the major problems is that the project investment is seriously over budgetary estimate. This article intends to make some discussion on this issue. First, the road project investment over budget analysis of the reasons for At present, the actual investment in highway engineering estimates is more than the Cape
