Tectonic stress near the surface of crust,which is measured and tested at home and abroad,is always affected by a few factors,and is overlapped by non-tectonic stress,e.g. stress caused by topography. Therefore,this paper has discussed the items needed to pay attention before and after crustal stress measuring. Before the measurements,we should focus on the determination of measuring sites and on the influence of the factors of landform,rock types,fractures,and so on. After the measurements,an analysis on the reliability,the correction and comparison,and the representative of the measuring values is necessary. The variation and difference of local crustal stress states should be considered at different structural sites,different rock types,different rock mass constitutions,different depths and so on along underground engineering route line. In addition,the variation of local crustal stress states caused by different engineering design texture,size and so on should also be taken into consideration.
