摘要
该区属岩性较简单,构造较复杂的地区。新发现的较大断层8条。对工程产生较大影响的是F4和F18断层。测区内发现磁铁石英岩残留体、粗面斑岩、大理岩、钠长岩等新岩石类型。原设计主洞线F_5—F_6之间洞线将平行F_4穿越330m的断层破碎带。我们建议优化洞线避开断层破碎带,使遂洞穿越工程地质条件较差的浪子山组二云片岩的距离减少1600m,洞线总长度不变,支洞亦可布置,达到优化的目的。
The lithological characters are comparatively simple and the structure is comparatively complex in the area. There are eight faults that have been found recently. Fault F4 and Fault F18 have great effect on the engineering. The new type of rocks such as the residuum of magnetite quartzite, trachyte porphyry, marble and sodaclase are found in the survey area. The main tunnel line that is designed originally between Fault F5 and Fault F6 will parallel Fault F5 and go through 330-meter-thick fault slacking zone and it is very harmful to the tunnel. We suggest optimizing the line in order to avoid 330-meter-thick fault slacking zone and reduce the distance by 1600m which the original line will go through the bad engineering character of the rocks. The total length do not change and it will realize optimization.
