摘要
哈尔滨市区自７０年代末开始大规模开采地下水致使地下水位大幅度下降，水位降落漏斗不断扩展，漏斗中心处的部分建筑物发生不同程度的裂缝和变形，个别路面发生不均匀沉降。本文对哈尔滨市区可能产生的地面沉降问题进行初步分析，并提出有关防治措施的建议。
The wide scope development of ground water has been started since the end of seventies in Harbin f which leads to a sharp decline of ground water table and a continuously expansivecone of depression. For this reason,crackings and deformation of buildings can be found in the central area of this cone and uneven subsidence on road surface was occured. In this paper, elementary analysis of ground subsidence occured in the urban distriCt of Harbin is done and suggestions of preventive measures are put forward.
