为研究玻化微珠保温砂浆外墙外保温系统在夏季和冬季环境下的温度和应力，基于热分析理论并利用 ANSYS 有限元软件对保温墙体进行了模拟分析。结果表明：玻化微珠保温砂浆具有优良的保温隔热性能，无论是夏季高温还是冬季低温，均能使室内温度保持稳定，其温度浮动在2℃以内；由于冬季室内外温差大，在冬季环境温度作用下，保温系统外表面温度应力比夏季环境下增大了83％；沿墙体厚度方向的应力分布，抗裂砂浆层应力最大，保温层应力最小。

In order to study the characteristics of the temperature and stress conditions of the exterior insulation systems with thermal insulation glazed hollow bead mortar in the summer and winter environment,the behavior of the thermal insulation wall was analyzed by a commercial finite element software ANSYS based on the theories of thermal analysis.The results show that the thermal insulation glazed hollow bead mortar has excellent insulation properties,which can keep indoor temperature stability within 2 ℃.Due to the temperature between indoor and outdoor in winter,the thermal stress on the surface of insulation systems is 83% higher than that in summer.The stress in anti-crack mortar layer is biggest and insulation layer is smallest along the thickness of the wall.
