摘要
福建漳州—龙岩高速公路龙岩段石崆山II号高架桥经过工程地质条件复杂的岩质高边坡地段。该边坡岩体发育有3组优势结构面J 1,J 2,J 3,分别以单结构面与边坡面组合、两组优势结构面共同与边坡面组合,以及3组优势结构面共同与边坡面组合进行赤平投影分析,综合判定自然边坡基本稳定。对自然边坡及拟开挖的人工边坡进行SARMA极限平衡分析,定量判别该高边坡整体处于稳定状态。
The viaduct No.II of Shikongshan in Zhangzhou—Longyan expressway is located at a high slope with a complicated engineering geological condition. There are three sets of dominant structural plane J1,J2developed in the high slope rock mass. The combined slope plane with single dominant structural plane of rock mass,two sets of dominant structural plane and three sets of dominant structural plane,is analyzed by Stereographic projection respectively. The result shows that the natural slope is basically stable. Furthermorestability of slope to be excavated and natural slope is evaluated by SARMA limit equilibrium method,the high slope is also considered steady.
