1 水利工程造价上涨原因分析1.1 自然条件的变化 一般说来,水利工程开发的规律是先易后难。前期开发的水利工程,在交通运输条件、地形地质条件、施工条件等方面往往较优越,后期兴建工程的难度相对来说要大些。如我省入海河口兴建的水库工程,其坝基高喷灌浆及其造价是过去工程所没有的。1.2 建筑材料价格的变化 水利工程造价中,建安造价约 1 Analysis of the causes of rising water conservancy project costs 1.1 Changes in natural conditions In general, the law of water conservancy project development is the first easy hard. Hydraulic projects developed in the early stage tend to be superior in terms of traffic conditions, topographic and geological conditions, construction conditions, etc., and the difficulty of later construction is relatively larger. Such as our province into the estuary of the reservoir construction, the dam foundation high jet grouting and its cost is not in the past projects. 1.2 Changes in the price of building materials Water project cost, Jian An about cost
