    Abstract: Civil infrastructure provides the physical backbone of all societies. Water supply, wastewater treatment, transportation systems, and civil structures must be sustainable over multiple decades (e.g. 20, 30, 50 years) for human populations to survive and flourish. Over such a long time-period, climate changes are inevitable. The global atmospheric s... Show More

    Abstract: Pedestrians are an important element of the traffic stream especially in a country like Bangladesh. Dhaka is the biggest metropolitan city of Bangladesh and thus people from different parts of the country are relocating to Dhaka. This has rendered Dhaka one of the most densely populated cities in the World. With the resource restraint and crumbling... Show More

    Abstract: The steady ability of sandy pebble stratum is poor, during the tunnel construction, landslides occur frequently. In order to clarify the mechanism of landslide in sand gravel tunnel and put forward effective treatment technology, the paper takes the Gongboxia tunnel, which located in Qinghai Province, as the engineering background. In view of the l... Show More
