Abstract Based on the principle of finite element method，combined with the practical problem of Niuhushan tunnel，which is six lanes of double lines，a freeway from Huizhou to Shenzhen in Guangdong Province，some numerical tests are conducted to analyze the stress condition of the tunnel in fault，and the influences of fault position on the construction mechanical response are studied. Some distribution rules of surrounding rock stress of large-span tunnel are summarized to provide the reasonable references to design and construction of this tunnel and similar engineering.
