There are a series problems that are caused by the complex geological and various types of foundation soil of the canal during the excavation process in the first stage of the South-to-North Water Transfer Project, such as the different strength of the same rock, especially the undulating boundary of the rocks and the varying buried depth. The author made a detail research on the spatial distribution of the basic rocks and the calculation for the volume of the excavation to save the problems and calculate the excavation volume of the rocks with different strength, also the cross and vertical method were used to provide the necessary technology data and a technology support for planning and programming of project construction.

This article selects the typical carving stone as the research object. We make an discuss about the factors affecting the effect of seal cutting art of using saber from the perspective of petrology through the conditions of seal cutting stone material, color, hardness, transparency and so on. Making an analyze about the adaptability to seal cutting stone and the stone material impact bit broken seal treatment , in order to select material of seal cutting lovers with reference.
