Study On Effect Of Permeable Pavements On The Thermal Environments In Residential District

With the process of urbanization and metropolitan allies is accelerated，people becomemore and more concerned about the increasingly exasperating of the environment.In particular, outdoor thermal environment of modern residential area close related toour daily life. Creating a favorable living environment is of great significance, so it isnecessary to study the influence on the each design factor for the thermal environment of theresidential area. This paper mainly researches influence of the pervious brick ground onoutdoor thermal environment of residential area.The main contents in the paper are as follows:（1）Through research analysis to the residential area on the public ground area and thematerial of public activity ground, the paper summed up that there are plaza，recreationalground，aboveground parking and pavement which are people used most outdoor in theresidential area.The four kind of ground are mainly studies in the paper.（2） According the permeable ground features and structure, the paper summaries theconcept of ground permeability. By testing the permeability of pervious brick and the surfaceof pervious brick ground, the value of ground permeability is come up with investigation ofrelated fields and related test.（3） Using thermal environment software DUTE simulated the value that different areapervious brick ground impact on environmental temperature. By employee themathematic model to calculate influence of the pervious brick ground on outdoor thermal,the factors are area and evaporation of the pervious brick ground. According the typicalmodel and actual cases，the following conclusion were drawn:The influence that pervious brick ground impact on environmental temperature isa linear function.With the more ratio of pervious brick ground, temperature is decline. Thearea ratio of pervious brick ground is more, the ratio of linear function is bigger.The centralized large area of the pervious brick ground is better than disperse small areain influence of the pervious brick ground on outdoor thermal environment of residential area.The value of influence that pervious brick ground impact on environmentaltemperature range from0.2℃to0.4℃.The pervious brick ground is used as study object to research the influence of thepervious brick ground on outdoor thermal environment of residential area.This paper provideda design conduction of outdoor thermal environment which is take an important part in the outdoor thermal environment design which have directive significance for residential designin future.
