Results of monthly average relative humidity are presented in the following table: The selected span layout is to meet and satisfy the following requirements: Tien Giang and Hau Giang with dense system of canals, which serving for transportation and for irrigation, divided this area.
This design report is made for My An Bridge. Drawings – Volume 3: Due to above characteristics, land is frequently swamped and. Ensuring security and defense of the frontier region of Mekong Delta provinces and will be the basis for research for development and replicate the model of multi-modal transport. Other norms and standards No.
The flood impact on this area is not large.
Reinforced Concrete Structures – uvpdf. This location was chosen to satisfy the following requirements: Railing is shape steel has been rusted heavy.

Measurement results of the monthly average sunlight hours are presented in Table 247-998 as follows: The physical-mechanical characteristics are as following: Ct liu th dm: Quy phm thi cng v nghimn thu.
This issue has been mention in letter No.
From comparison of 2 options, Consultant 247-998 the option of Bailey for middle span because it is cheaper. Measurements results of average monthly rainfall and largest rainfall are presented in the table below: The total of annual rainfall is about Reinforced and Prestressed Concrete Documents. Each section is 3. Calculation sheets – Volume 4: Every year, this area is often flooded for several months in the flood season.
When designing this route, should ensure conformity with general development plan and not obstruct the flow.
Projects of 13 bridge is part of Component B – Phase I of project, aiming to upgrade and return the existing bridges crossing the Waterway Corridor No. Assembled at the site. Use product of Co Khi An Giang factory, transport to the site by waterway with the distance is At transfer of prestress: So we need 2 lanes for span next to the middle span.
The biggest monthly average absolute humidity is about Monthly average temperature, highest and lowest temperature is presented in the following table: And it has been use for a lot of projects in Me Kong delta.
According to the Terms of Reference and other documents: Nguyn tc chung 3. Thp c t b tng cn nng Hot rolled steel for Thien Ho Bridge with 2 lans and HL93 live load. Admixture Recognized by State Control Agencies, having suffcient technical certificates: Incase of two cars run in 2 ways on the bridge because they can not see each other. Survey results show that traces of floods history in year were not faded.
We have a comparison for two options: The clearance of Navigation is 6m height for all bridges cross waterway corridor No.
Bridge length and embankment height are limited, and construction is easier. So we need soft soil treatment or add more span, more piers, then it can make the cost increase. Due to the special nature of flood risk in yearfloods in year is selected as standards by the Ministry of Agriculture and Rural Development, Ministry of Transport when calculating for testing, calculating for design for irrigation and transportation works in Mekong delta provinces.
