In order to study the strength and failure characteristics of sandstone with mudstone interlayer. According to mudstone interlayer dip and distribution form, it can be divided into three kinds of sandstone: sandstone with horizontal mudstone interlayer is Class I; sandstone with inclined mudstone interlayer is Class II; sandstone with irregular distribution mudstone is Class III. The three kinds of sandstone uniaxial test were carried out and combined with the theory of layered rock mass failure, it revealed mechanical properties and failure mechanism of sandstone with mudstone interlayer. The results show that: crack generated from interface in Class I and II and crack generated from irregular distribution mudstone interlayer in Class III; The sandstone with higher strength is destroyed before the mudstone interlayer; sandstone at unbonded interface is failure before sandstone at bonded interface; Three kinds of sandstone vary in compressive strength, Class II is greater than Class III while Class III is greater than Class I.
