【摘要】 该文通过地面沉降与地下水头降深之间的线性相关关系来确定临界水位,并将其与根据超固结应力确定的临界水位进行比较,结果表明:两种理论依据下提出的临界水位具有相同的物理意义,仅在值域上存在一些差异。就其准确性而言,通过地面沉降与地下水头降深之间的线性相关关系确定的方法明显具有较高的可信度,值得进一步推广。更多还原

【Abstract】 In the paper,the critical water lever is determined according to the linear cor re lation between land subsidence and groundwater drawdown,simultaneously,as comp ared with the critical water level by preconsolidation stress,the results show t hat their physical meaning is agreeable for two methods of acquiring critical w ater le vel,only exist some differences on value domain.As for their accuracy,the new me thod has obvious credibility and superiority to others,which is worthy to be fur ther popularized.更多还原
