*加瀬 駿介1、杉岡 弘一1、星住 哲也1 (1. 阪神高速道路)

Keywords:measures against water leaking, lower roadbed, porous concrete, cement stabilization treatment

Water leaking occurs at part of Yamatogawa route. We tried measures against water leaking, but we could not stop water leaking at all area. Therefore, we introduced water introducing system by porous concrete, cement stabilization treatment and so on. The design concept is that “we introduce water introducing system at roadbed and “we apply the roadbed with high durability for water leaking”. This paper reports that measures against water leaking at bottom slab of the open cut tunnel.
