新建吊钟水库天然建筑材料地质勘察分析评价

Geological SurveyAnalysis and Evaluation of Natural Building Materials in the Newly Built Diaozhong Reservoir

在水利工程中,天然建筑材料是决定水库建筑物选型和工程造价不可或缺的决定性因素。在分析新建吊钟水库库区地形地貌、地层岩性以及不良地质条件的基础上,通过地质调查、钻探、坑探等勘察手段,结合野外和室内土工实验、化学成分、岩矿鉴定检测、碱~硅酸反应活性试验等方法,对可研阶段推荐坝址设计需要建坝的各种建筑材料的物理、力学性质指标及储量进行评价分析,为水库建筑物的最终选型提供重要的参考依据。

In water conservancy engineering,natural building materials are an indispensable decisive factor in determining the selection of reservoir buildings and engineering costs.This paper analyzes the topography,lithology,and unfavorable geological conditions of the newly built Diaozhong Reservoir area.Through geological survey,drilling,pit exploration and other exploration means,combined with field and indoor geotechnical experiments,chemical composition,rock ore identification and detection,alkali silicic acid reaction activity test and other methods,this paper evaluates and analyzes the physical and mechanical property indicators and reserves of various building materials recommended for dam site design in the feasibility study stage.It provides an important reference for the final selection of reservoir buildings.
