Study On Restoration Design Of Eaves Of Stone Caves In Maiji Mountain Grottoes

Maijishan grotto art is a comprehensive art including grotto frescoes,statues and buildings.This architectural image is built in front of the grotto or carved out of the cliff wall of the wooden or stone structure outside the eaves of the building,also have cliff pavilion,house grotto and so on.There are nine caves with eaves in maijishan grottoes,numbered no.1,no.3,no.4,no.5,no.28,no.30,no.43,no.49 and no.168.These nine caves,concentrated in the east cliff.In the history of maiji mountain,there are probably more caves with eaves than nine.Many caves in the central part of the cliff have cave eaves.We found both at home and abroad literatures at home and abroad for dunhuang grottoes research in the field of architecture in detail is Fu Xinian teacher,teacher Fu Xinian in reflected the maijishan grottoes in the north building,the article of maijishan stone KuKu eaves construction detailed and systematic investigation,measurement,and mapped the wat XianMiaoTu eaves,and 3,4,49 wat wat to collapse eaves reconstruction research,but not in-depth study of rehabilitation design and detailed design,so the current research on stone maijishan KuKu eaves construction also has shortcomings.This paper first analyses the maijishan grottoes cultural relics of the occurrence of the environment,the geological characteristics of the region,temperature and humidity,and light climate characteristics: maijishan located in east longitude 106 °,latitude 34 ° 21 ',either altitude 1671 meters,belongs to the warm temperate humid and semi-humid climate zone;Maijishan scenic area vegetation lush,damp climate,most of the average temperature is-3 ?,the most thermidor average temperature for 19 ?,annual average rainfall of about 800 mm-1000 mm,rainfall concentrated in 4,in September,the average relative humidity of 70% or so.Area belongs to China climate region of the first ? light climate zones,annual sunshine hours < 2700 h,and each year the sun sunshine > 6 h the number of days in more than 155 d.In this paper,the maijishan existing nine wat eaves construction according to the nature of the facade and the function,stone,eaves column shape and aperture and eaves column combination way,shape,analyzed and classified,and then to the current situation of the nine wat eaves are briefly described and analyzed,and the first 43 wat,wat,wat,wat,30,49,wat,wat,five were measured,and draw the CAD flat vertical profile drawings according to the measured data.Paper choose the maijishan grottoes wat 4 repair for reconstruction design of the research object,according to the site investigation and surveying and mapping,with reference to the seven studio hip roof top,according to the ancient book record and reviewing previous studies of finishing this paper,the four wat,wat from diggings gallery,roof,wat eaves and after room and so on are studied,using CAD drawing the flat vertical section,and Skechup restoration model is established.Finally,on the basis of the third ZhangJianLi 4 wat restoration model size,respectively,set up four wat,wat,eaves and simplified model without wat eaves,Ecotect daylighting simulation and Phonenics air changes,integrated two of software simulation results,to analyze wat eaves and wat corridor on the stability of the grottoes environment regulation function,verify the necessity of wat eaves construction recover repair design.
