According to the construction of the twin-arch tunnel of Xiaojinkou,by the statistical analysis of the measurement data of the section 1-1 in the class Ⅱ surrounding rock masses, the mechanical models of the structural members in the twin-arch tunnel are proposed, including the model of the contact stress between the surrounding rock masses and the first lining,.

Based on the cases of the Xiaojinkou twin-arch tunnel of Guangzhou-Huizhou Highway and the Xiedipo twin-arch runnel of the Yibin-Shuifu Highway, the elastoplastic model of the plane stain is established and the elastoplastic behavior of the construction of the twin-arch tunnel is simulated and analyzed by the finite element.

The article introduces the two twin-arch Tunnel-ChaDao One Tunnel and ChaDao Two Tunnel on the ZhangShi freeway during the second periods from Huashaoying to YuXian.
