通过结构面的数学建模，使采集所得结构面数据的处理实现了信息化，程序化，应用多功能数据库在计算机上人机交互划分岩体结构，初步实现岩体结构的信息化，并且通过结构面与相关实体的真三维实体模型的建立，既可清晰直观的展示结构面模型的空间形象，又可容易的切割模型并获取切图的数据，对不稳定块体的分析研究提供了强有力的辅助手段。

The ESEU website includes information about ESEU activities. Worksheets for teaching earth sciences at key stages 3 and 4, used in INSET training, are available from the site. The documents (in PDF format, requiring Adobe Reader) cover topics such as the rock cycle, rock identification, the changing Earth and atmosphere, plate tectonics and outdoor activities. Resources available on the site include: a virtual rock kit with images of sedimentary, igneous and metamorphic rocks; links to related sites; and recommended textbooks.

Owing to inborn high temperature and high pressure gas after blasting and complexity of dynamic principal relationship and interact ional complexity between dynamite and rock and non-equal character and anisotropies of rock, the rock blasting mechanism research is quite complex.

该过程由于炸药爆炸后生成的高温、高压气体产物和岩石动态本构关系的复杂性，炸药与岩石之间相互作用的复杂性，以及岩石本身的非均质性和各向异性等使得岩石爆破机理的研究显得十分复杂和困难。

Laxiwa Hydropower station is located in a high mountain valley and narrow valleys, where the regional geostress field is higher. Besides, local existence of tectonic fracture zone and size of large-scale excavation are common phenomena in this project. The surrounding rock of hydropower plant is mainly granite, which are hard and brittle rock, this kind of rock is very detrimental to the stability of the cavern.

拉西瓦水电站厂房地处峡谷山高坡陡，河谷狭窄，区域地应力场较高，局部存在构造破碎带，同时开挖尺寸规模巨大，围岩主要为脆硬的花岗岩，对洞室稳定极为不利。

The mantle of original rock is the base carbonate rock and transition rock.
