Body Theory Analysis And Software Development

The left and right tunnel will influence each other in construction of closely -spaced tunnel, it is key to success that middle rock body is reinforced. Body theory is one of the effective methods of the stability for analyzing the non- continuous body. Firstly body theory regards the structure face as the interspace face, regards structure body as the protruding body, regard effect loading as interspace vector, with the geometirc method(analysissitus and set theory), researches how many kinds of body types and mobility under the condition of every known space level, secondly, with the method of the fix calculation, obtaining motive force of pieces of body of all kinds of unstable body, it has three kinds of analyzation: vector method, graphic method and stereo-analytical method. Because the calculating amount is too big if the vector method is used and the accuracy is difficult to guarantee if the graphic method is used, which are difficult to be mastered by engineers and technicians. The stereo-analytical operation of body theory is to combine the above two kinds of methods, which have expanded the applicable scope of body theory greatly.According to the data relevant to Heshang tunnel, one of expressway in Fujian, and based on the geologic drawing worked out in construction site. The text constructs entity models of tunnel and structural planes, and analyses the stability of blocks which are made of tunnel freefaces and the structural planes in rock masses with stereo-analytical operation. All the results have been obtained at the promise of having made sure the location of discontinuity. On the research results of this thesis, we apply the stereo-analytical method of body theory to analyze the rational construction order of the closely -spaced tunnel, which have offered scientific basis for rational excavation of the closely -spaced tunnelIn order to make stereo-analytical to be applied to scientific research, production conveniently, the author has carried on the software development to analyze of the project in Windows operation system. In software development, Visual C++ is regarded as the platform. This software has offered several convenient interface, it can realize several function, including data input, calculation, etc.. In this text we compare result of calculation of this software and the destroy situation from the geological record, which proved that the result of calculation is reliable. By using the system, we can obtain the results quickly and exactly instead of doing complicated things. So it is a good way to study the stability of block in closely-spaced tunnel.
