| 摘 要： | 1556年华县大地震，在渭南市区产生了大量的地震裂缝，研究与工程实践表明，这些裂缝遗迹目前已处于稳定状态。随着地下水位的普遍下降和上覆土层的加厚，在基本烈度为Ⅷ时，市区内一般将不会产生砂土液化等震害现象。拟建场地出现此类裂缝，只需采取相应的岩土工程措施，便可做为适宜建造场地。应将地震裂缝与由构造引起的地裂缝及由湿陷性土遇水引起的湿陷裂缝区别对待。

| Abstract: | A great of seismic fractures were produced by the major earthquake in Hua county in 1556. These fractures are now in steady state by studying for actual engineering' Because of groundwater lowering and over soil strata thicking, the earthquake hazards (such as sandy soil liquefaction) will not take place in the urban district under the condition of seismic inten-sity of . When these fractures occurred in the construction site which were drew up, it is must to be taken measures of adaptive engineering, so as to obtain good construction site' It is suggested that seismic fractures are different from geofractures resulted by structure, and wet depressed fractures which were resulted from wet sinking soil met water. |
