一、前言在我国的平屋面中,目前大多仍采用传统的二毡三油屋面,但由于此种屋面的使用年限短,渗漏现象严重,维修、返修困难,已成为基建、维修部门的一个老大难问题。根据原城乡建设部有关部门对全国五个大区的调查表明,从1971～1980年间完成的卷材屋面从竣工到开始维修平均仅三年,最短的只用了半年就渗漏,如上海抽查139栋住宅的卷材屋面有渗漏的占42%。卷材屋面产生渗漏的原因,主要是因油毡开裂、鼓泡、老化的结果。产生这些问

In the 139 houses, 42% of the membrane roof leaked. The reason for the leakage of the membrane roof is mainly due to the cracking, bubbling and aging of the felt. Generate these questions
