| Urban space form is the most important content in urban design,which reflects the layout and style of the overall space.With the continuous transformation of urban design to the fourth generation,the application of digital methods in urban design is becoming increasingly widespread.The rich and diverse natural landforms in mountainous environment increase the difficulty of traditional urban design,and the digital method makes urban design more scientific and accurate with its high efficiency,visibility and interaction.Through the application of digital method to simulate,analyze and generate the spatial form under the control of different parameters,the efficiency of urban design can be greatly improved.This study takes Gongyi Square Town as the research object,takes shape grammar as the main generation principle,takes Arc GIS + rhino + grasshopper as the generation platform,integrates the basic information of planning and design,and explores the advanced digital generation process of artificial settlements in mountainous conditions through simulation generation and visual expression.This paper consists of four parts.This thesis consists of four parts as follow:In the first part of the thesis,this thesis analyzes and interprets the relevant theories and research of morphology,specifically studies the application principle and process of shape grammar,and explores the ideas and logic of applying shape grammar to the generation of urban morphology,so as to provide theoretical basis and foundation for the generation of spatial morphology.In the second part of the thesis,the thesis analyzes the basic situation of Gongyi Square Town project,loads information datas in Arc GIS + Rhino platform and constructs the informatization model of the Square Town.Through the analysis and summary of the design control elements,the thesis clarifies the urban design goal of Square Town,and then clarifies the target form of spatial form generation.In the third part of the thesis,the thesis analyzes the morphological characteristics of cluster spatial form in mountain environment,clarifies the plane structure layout and vertical hierarchical organization of the cluster spatial form,sets the generating principles of Square Town form combined with the principle of shape grammar,sums up three generating grammars of monomer combination,vertical grounding and interface control.According to the generating principles,the thesis translates these three generating grammars into the shape set(S)and the rule set(R).In addition,the specific application process of shape grammar in the formation of Gongyi Square Town spatial form is determined.In the fourth part of the thesis,the thesis,according to the design sequence of "plane shape generation—vertical texture organization—interface combination control—scheme deepening design",takes Rhino + Grasshopper as the generated platform,and simulates,designs,analyzes and visually controls the shape generation tools in each process.Through the parameter inspection and control in each stage of the advanced generation,the simulation model of the spatial form is obtained,and on the basis of this simulated spatial form,the deepening optimization design is carried out,and then the Square Town spatial form based on the shape grammar is obtained.Through the research,the following conclusions are drawn: the "cascade" information model integrating the basic design conditions is constructed;The grammatical rules of cluster spatial morphology growth in mountain area are determined;The digital urban design process of "information quantification generation simulation design deepening" is explored. |
