地下建筑物设计的重要特点可概括为：①独特的隧洞设计；②合理的施工工艺和支护结构方案；③地下工程结构布置方案；④不同工程地质条件下隧洞结构计算方法的确定；⑤地下建筑物的４个设计阶段。对上述特点作了详细叙述，并指出结构设计方案要利用现场调查和地质勘测资料予以修改，最后设计方案要经专家或技术会议结合具体情况鉴定通过。
The main features of the design of underground buildings can be summarized as follows: ① unique tunnel design; ② reasonable construction technology and support structure program; ③ underground structure layout program; ④ under different engineering geological conditions to determine the calculation of tunnel structure; ⑤ underground 4 design stages of the building. The above characteristics are described in detail, and pointed out that the structural design scheme should be modified by on-site investigation and geological survey data. The final design proposal shall be approved by experts or technical meetings according to the specific conditions.
