Based On Fractal Theory M Project Service Pipe Net Plan Research

Survey and design industry in China with the deepening of reform and opening and socialistic market economy gradually establish and are constantly adjust, formed the state-owned, collective and private enterprises and joint ownership, different pattern of diversified assets. Joining the WTO, reconnaissance and design industry faces more challenges, domestic and foreign design units, promote technological innovation competition, improve the design quality has become the design enterprises in market competition.A unit is a company, engaged in the planning and design of urban planning, and the zoning planning, the regulatory detailed planning and construction detailed planning of different levels of planning. In the regulatory detailed planning process, water supply project network planning, the main problems for water supply network layout design according to the planning and land by the situation, completely by subjective experience along the road layout water distribution network, network density and too little, too, and lack of measure.Therefore, in planning and design personnel in the lack of water distribution network planning and layout of quantitative evaluation index, the related articles introducing the theory of fractal theory, the formation distribution network model from aspects of the inherent law of aspects, water distribution network planning, optimized design of improving the quality of products.This research mainly adopts the process in the box counting method for calculation of water distribution network of fractal dimension, then according to the fractal dimension of the evaluation of the planning design results, which can evaluate the direction of water distribution network layout optimization, and through the optimization, examine to judge whether the desired effect.Combining with practical engineering in the water supply pipe into the fractal theory analysis, the latest scientific theory applied to engineering practice to planning and design enterprises is a kind of technology innovation, and project itself, based on fractal theory of network design optimization, make water distribution network planning and design more scientific achievements.
