The Research Of Intelligent Design System In Tunnel Blasting

The blasting technique is applied in most of tunnel construction in our country. The quality and velocity of the tunnel blasting design can directly influence the safety, quantity, cost and work period. At present, there are still the current predicaments that the design determined, blasting parameters selected and calculated by the designer's experience, handwork drawing, adjusting and also those problems. Therefore, to develop an intelligent tunnel blasting design system has important value in application function.Design of the blasting parameters in tunnel system based on visual basic is one of the important subjects in the realm of the water conservancy project. The present paper is a preliminary study of the design system of the tunnel blasting. Using Visual Basic, the research develops the suitable application blasting software, will make some beneficial explorations and the attempt for the later further deep research. In this Paper, the Visual Basic 6.0's internal control is made use of establishing a tunnel excavating windows, and applies Visual Basic to realize each control effect. The geology condition and various parameters are input it and choosing corresponding blasting methods. Different blasting methods chooses the different the formula blasting and parameters, parameters are calculated and output according to editing a code and setting up an attribute. According to tunnel dimension, form, the network graph of tunnel blasting is drawn by VisualBasie6.0's pictures functions. Employ this design system, carried on the test to the Tiansheng bridge first-level hydroelectric power station tunnel. The system possesses friendship interface, handiness, strong commonality and easy maintenance. Realize the request of that design the tunnel blasting parameters by VB.
