摘　　要：当前国内山地资源利用不足,充分利用山地优势的嵌入式山地建筑营造理念值得借鉴。本文以重庆典型嵌入式山地建筑华岩洞为例,通过热环境实测分析全年各季热湿环境,并比较室内包括山体在内的各壁面与室内空气的热交换,解析山体对室内热环境的调节机制。结果表明:由于直接利用山体作为建筑的部分墙体和屋面,嵌入式山地建筑在夏季表现突出,室内温度在室外温度同等变化下比其他季节更稳定,但室内湿环境全年不理想。山体温度全年稳定程度大于室内其他壁面,室外空气温度每升高1℃,山体仅升高0.46℃,其对室内热环境的调节能力在冬季和夏季都较显著,且夏季最强,是过渡季的4.8倍。山体调节室内热环境的能力大小与接触室外空气的程度紧密相关,夏季山体部位越靠近地面,壁面温度越稳定,吸热强度越大,山脚在室温最高时内表面热流强度高达50.0 W/m^(2)。The mountain resources are not fully utilized in China nowadays,therefore it is of significance to study the concept of embedded mountain buildings that making full use of mountains.Taking Huayan Cave,a typical embedded mountain building in Chongqing,as an example,this paper analyzed the thermal and humid environment in each season of the year by thermal environment measurement,and compared the heat exchange between the indoor walls(including the mountain)and the indoor air,so as to interpret the regulatory mechanism of the mountain on the indoor thermal environment.The results show that,as the mountain is directly used as part of the wall and roof of the building,the embedded mountain building performs well in summer,and the indoor temperature is more stable than in other seasons under the same change of outdoor temperature,but the indoor wet environment is not ideal throughout the year.The stability of mountain temperature throughout the year is greater than that of other indoor walls.For every 1℃increase in outdoor air temperature,mountain temperature only increases by 0.46℃.Its adjustment ability to indoor thermal environment is more significant in winter and summer,with the strongest in summer,4.8 times that of the transition season.The ability of the mountain to regulate the indoor thermal environment is closely related to the level of contact with outdoor air.The closer the mountain part is to the ground in summer,the more stable the wall temperature,and the greater the heat absorption intensity.The inner surface heat flow intensity of the mountain foot at the highest room temperature is as high as 50.0 W/m^(2).
