摘　　要：1997年8月,濮阳县胡状乡几个村庄相继发生地裂缝。经过详细调查研究,得出是由于干旱引起地下水位下降,浅层土体收缩并产生不均匀沉降而致,并非构造成因的结论。以后几年,濮阳县柳屯等地也发生过同样地裂缝,验证了这一结论。这项工作为研究濮阳地区大面积干旱而产生的地裂缝提供了实例,对区分是否构造成因地裂缝有一定的参考意义。同时对建设部门规划和处理房屋地基具有实用价值。In August 1997, ground cracks appeared in succession in Huzhuang township of Puyang county. Researches have been carried out to find out that the ground cracks were caused by water table drops, but no by nectonic activities, and nonuniform settlement of soils at shallow depths. In the next several years, ground cracks took place in Liutun township of Puyang country too, which verifes this view. This study provides an example for investigating ground cracks due to arid in large areas in Pyuang country, and is useful to distinguish whether ground cracks are formed tectonicly. It is also of value in construction plan and housing ground improvement.
