As an important form,pile-anchor retaining structure is widely used in foundation pit,but some problems still exist in design schemes that will cause hidden danger and unnecessary waste because structure calculation and constructional measures are unreasonable.Through the discussion about some easily confused problems in question such as pile in row,anchor(cable),top beam,middle beam,this article obtains some design work experience for readers' reference.%桩锚支护结构作为基坑支护的重要形式应用较广,但不少设计方案中涉及结构计算与构造措施的内容不甚恰当,造成设计安全隐患或不必要的浪费.通过对桩锚支护结构中排桩、锚杆（索）、冠梁、腰梁等构件受力、变形计算及部分易混淆问题的探讨,得出部分设计经验供参考.
