Based on ANSYS software, combined with the practical problem of weather deep troughs foundationtreatment scheme of Zhuzhou navigation and electricity junction engineering-concrete arch above on the deepweather troughs, preliminary analyses were conducted concerning characteristics of stress and strain distribution inthe concrete arch before and after sluice in front of the upper structures.

Based on the project of Xinyajiang Bridge of Panzhihua, the dissertation makes a tentative research into the seismic performance of long-span reinforced concrete box-typed arch bridge and its seismic control(No:50578168).
