某公路隧道塌方原因分析及其处治

Reason analysis and treatment of some highway tunnel collapse

结合广东某高速公路隧道塌方段概况,分析了隧道塌方的原因,对塌腔处理方案设计、回灌混凝土厚度、缓冲层厚度设计和隧道结构设计进行了重点论述,通过以上方案的处理,塌方段得到及时处理,对塌方量大,地质条件差等特殊塌方事故的处理具有借鉴意义。

Combining with the general situation of some highway tunnel collapse section in Guangdong, the cause of tunnel collapse was analyzed, the collapse cavity treating scheme design, and recirculation concrete depth, buffer layer depth design and tunnel structure design were discussed importantly. By treating the above schemes, collapse section was treated immediately, which has guiding meaning for treating special collapse with large collapse and poor geological conditions.
