亳州盐渍土的分布及其工程地质特征

盐渍土是气候、地貌、地质、工程地质、水文地质等因素综合影响的工程地质灾害,本文在大量调查、分析与研究的基础上,采用了槽探、水样(水化学分析)、土样(土壤含盐量分析、土壤毛细水试验)等综合方法,分析了亳州盐渍土灾害的危害性及对农业生态系统、公路建设的影响,同时,考虑到人为和环境地质因素对盐渍土的影响,圈定了盐渍土的潜在威胁区,从而,预测了盐渍土的发展、演变趋势,因地制宜地提出了整治盐渍土的基本对策与措施。

DISTRIBUTION OF SALINIZED SOIL IN BOZHOU AND ITS ENGINEERING GEOLOGICAL CHARACTERISTICS

Soil salinization is engineering geological hazard jointly caused by climate,terrain,geology,engineering geology and hydrogeology, this paper based on a number of investigations and analyses,the effects of salinized soil hazards with expressway and agro-ecosystem are analyzed using test trench,groundwater sample(water analysis),soil sample(total-salt content analysis,capillary lift test of soil)medium simultaneously.This article generally recounted the length harmed by salinized soil along the Bozhou-Fuyang expressway,roughly 0.8km, and also delimited the area in hidden trouble due to salinized soil,with the influence of human and geological factors to salinized soil being taken into consideration.Thus,the evolution trend of salinized soil is predicted,a few countermeasures suitable to local conditions are presented for controlling soil salinization.
