摘要/Abstract

摘要： 水利工程具有高度线性化的特征,相较于建筑工程,水利工程中的单体具有结构简单且其规模较大的特征,这使得调整单个构件截面尺寸可以对工程总造价产生显著影响。针对水利工程中的挡土墙,研究截面选型,应用现在常用的GEO5岩土分析软件,对不同高度条件下挡土墙的受力进行分析对比,同时结合材料用量,应用广联达GCCP等计价软件,对不同截面形式的挡墙进行造价分析对比。结果显示,在3.2~4.2 m高度条件下,软弱地基上重力式挡土墙每延米造价由0.63万元增至1.48万元,悬臂式挡土墙每延米造价由0.58万元增至0.71万元,选用悬臂式挡土墙的经济性要高于重力式挡土墙。

Abstract: Water conservancy projects have highly linearized characteristics. Compared with construction projects,the individual units in water conservancy projects have the features of simple structural forms and large individual scales. The characteristics of water conservancy projects make the adjustment of the cross-sectional dimensions of individual components have a significant impact on the total project cost. This paper conducts a cross-sectional selection study on retaining walls in water conservancy projects. Using the commonly used GEO5 geotechnical analysis software,the force analysis and simulation comparison of retaining walls on soft ground under different heights are carried out. Combined with material consumption,the cost analysis and comparison of retaining walls with different cross-sectional forms are conducted using cost calculation software such as Guanglian GCCP. The results show that under the height condition of meters to 4.2 meters,the cost per linear meter of gravity retaining walls on soft ground increases from 6,300 yuan to 14,800 yuan,while the cost per linear meter of cantilever retaining walls rises from 5,800 yuan to 7,100 yuan. It can be concluded that the cantilever retaining wall is more economical than the gravity retaining wall.

Key words: section selection, force calculation, cost analysis, retaining wall
