摘要:由于电厂特殊的工作环境,其受到地质病害的威胁日益严重,对电厂区的地质病害进行研究治理显得尤为重要。根据灾害成因,将电厂场区的地质病害分为高边坡、滑坡和冲沟汇水三类,通过室内试验分析法,工程地质比拟法,中、浅层滑坡反演分析推导深层滑坡参数指标法、经验类比法综合确定,并通过对每个区域代表性断面的计算,选取合理的c、φ值,将病害区划分为五个区段进行治理,确定了经济合理的治理措施。实践证明,电厂场区地质病害性质及特征分析清楚,描述准确,计算参数选取合理,稳定性评价结果符合实际,设计治理措施得当、经济合理, 从根本上消除了地质病害给电厂场区带来的威胁。

Abstract: The geological diseases seriously threaten the power plant and the geological diseases in the field should be studied and theated. According to disease causes, the power plant site area of the geological diseases are divided into three classes of high slope, slope and gully catchment, through the indoor test analysis, the engineering geologic analogy method, the middle and shallow landslide inverse analysis method of deep landslide parameters is derived, determined comprehensively experience analogy method, and through the calculation of each region representative section, select reasonable c, φ values, governance disease division can be divided into five sections, the economic and reasonable control measures is determined. The practice proves that the characteristics and characteristics of geological diseases in the field of power plant are clear, the description is accurate, the calculation parameters are reasonable, the stability evaluation results are in accord with the actual situation, and the design management measures are appropriate,the economy is reaonable, it basically eliminates the threat of geological diseases to the poer plant.

当前正处在国内山区经济建设的高潮,山区基本建设工程中,保证高边坡、滑坡等地质病害的安全稳定,是一非常复杂困难,且尚未能很好解决的技术难题。

众研究工作者对黄土区滑坡成因与防治进行了大量的研究。在滑坡成因及滑动机理方面,王俊杰[1]在详细的野外现场勘察、整理钻孔探井资料、分析土工试验成果的基础上,对黄土滑坡形成地质环境条件、滑坡形成机理、滑坡稳定性、防治措施等方面进行了分析;刘世锋[2]对滑坡的分类、成因及机理进行了研究,并进一步对滑坡的发生条件和整治技术进行了研究,分析了黄土地区滑坡的特征、发生条件及诱发因素;……
