Abstract
21.9km of the route between Doi and Iyosaijo of the Shikoku Jukan (Transverse) expressway was chosen along the central tectonic line which is the largest active fault in Japan. Countermeasure works for slope faces were carried out attaching importance to ground anchor and reinforced earth works, and the section was completed on March 29, 1991. In the section, longitudinal alignment, plain alignment and road structure were reexamined to determine the center line so as to avoid landslide areas as far as possible, and much cost curtailment was realized for the landslide countermeasure works although there were many slope face collapses during excavation. The collapsed soil amounted to about 50 to 600m{sup 3} for one collapsed spot, with 1 to 2m average thickness of the slid layers. Reinforced earth work method was found to be effective for small to medium scale slope face countermeasure works. PC anchor or other landslide countermeasure works were required for large scale landslides which have the depths of slide exceeding 2m. 5 refs., 7 figs.
