摘　　要：川渝传统民居中利用通风架空地面防潮、改善室内环境是一种较为常见的做法,但通风架空必须有保证空气流通的孔洞、从而带来立面处理和防鼠、蛇等一系列问题。本文以空气间层的隔热、防潮原理为基础,结合川渝地区夯土民居的自身特点,提出了一种封闭空气间层的架空地面构造做法,对传统节能技术进行继承与改良。数值模拟结果表明,架空地面的内表面温度比普通地面的内表面温度高2℃左右,室内热环境得到了较大改善。It is a very common way to use ventilated raised floor to guard against damp and improve the indoor environment in the traditional folk houses of Sichuan and Chongqing. However,ventilated raised floor must be supported with openings for air circulation. This causes elevation treatment and a series of problems of protecting against rats and snakes,etc. Based on the thermal insulation and damp proof theory of air space,this paper considers the characteristics of the rammed earth folk house in Sichuan and Chongqing,and proposes a raised floor construction method with closed air space,which inherits and improves the traditional energy saving technology.The numerical simulation results show that the inner surface temperature of the raised floor is around 2 ℃ higher than that of the normal floor. The indoor thermal environment is largely improved.
