【摘要】 通过建立正演冻土模型,验证了将高密度电阻率法应用于冻土监测的可行性。对高密度电阻率法装置进行特殊处理,将其应用于对季节性冻土的监测,并进行了七个月份的连续监测。结果表明:高密度电阻率法在季节性冻土监测中可行;通过对实测数据进行反演处理,得到电阻率反演剖面,可以看出表层土壤在季节变化中有明显的结冻、解冻行为;并可估算出冬季冻土深度范围。更多还原

【Abstract】 The feasibility of applying high density resistivity method to frozen soil monitoring was verified by establishing a forward frozen soil model. The device for high density resistivity method was specially modified and applied in the monitoring of seasonal frozen soil for seven months. The results show that the high density resistivity method is feasible in the seasonal frozen soil monitoring. The resistivity inversion profiles can be obtained by the inversion processing of measured data,and the obvious freezing,thawing of surface soil can be seen in the seasonal variation. Moreover,the frozen depth range in winter can be estimated.更多还原
