transportation convenience degree and safety got people s extensive concern bridge modern traffic is the indispensable constituent at the same time the construction of bridge got rapid development in our country whether in the bridge engineering construction scale or in science and technology level are already among the most advanced countries in the world In the highway route is already open to traffic is a ferry highway Bridges and reconstruction of needs with socialist industry agriculture national defence and science and technology step by step also to realize the modernization of the urgent need to build many roads railways and Bridges here we the bridge engineering personnel will continue to face all kinds of design and construction of Bridges of arduous task Prestressed concrete beam bridge is our country road is widely used and has a long history of a kind of bridge structure type shape it grandiose and durable In recent years arch bridge cable stayed bridge such as suspension bridge built in China but a bridge for quite a long time is not provide lots of steel to build roads and Bridges the prestressed reinforced concrete simply supported beam bridge high strength steel T without crossing ability is bigger lower cost characteristic accords with current situation A A projectproject surveysurvey andand alternativealternative schemesschemes a a thisthis

in the region to 103 43 20 24 latitude 50 to 25 02 between main subtropical monsoon climate plateau Dry seasons the wet summer hot and humid and little rain dry Climate change significantly with altitude with vertical zoning characteristics For K94 for rock 000 to check points ZhuangTian section for at an altitude of 1000 to 1300 meters river valley and basin area the average temperature of 19 2 C C the highest temperature of 38 2 2 5 C minimum temperature the average annual rainfall of 795 mm average annual evaporation 1334 1 millimeter The route area rainfall and more focused on from six to nine months accounts for 66 to 83 of annual rainfall evaporation in 3 largest to may the highest temperature is 5 to July the lowest temperature is from December to February In general the route of regional climate characteristics are plenty of rain heat cold enough drought and the wind and weather disasters the light the less heat water allocation is reasonable 河北联合大学轻工学院河北联合大学轻工学院

the earthquake destructive earthquakes have nine times On December 21 1919 to the far 5 5 earthquake seismic intensity of 7 March 22 1929 in the east longitude 103 northwest 24 latitude 6 3 earthquake the earthquake intensity 8 degrees September 13 1950 a old 5 8 earthquake the earthquake intensity 8 degrees May 14 1953 small longtan happened 5 earthquake seismic intensity of 7 On jan 5 1970 the earthquake affected farming section caused part housing craze or destroyed Yunnan flat lock highway route area more than the earthquake happened in the west and the east is less The eastern region seismic intensity generally in 5 to 6 degrees relatively stable areas of basic The western region seismic activity have more frequent seismic time the decreasing trend all previous magnitude earthquake intensity of 6 to 8 degrees According to yunnan province earthquake team material now the seismological bureau of vertical crust deformation obvious relative changes of 50 mm the earth s crust that is still in activities belong to the unstable areas and destructive earthquakes may occur Yunnan flat lock highway route in the western region the epicenter of the earthquake frequent activity in north and south to fault zone and open the distant parts of the structure of fonts hinged compound and with hot spring out of the dew According to the Chinese the seismic intensity zoning map and different counties in yunnan province the seismic intensity zoning 河北联合大学轻工学院河北联合大学轻工学院 河北联合大学轻工学院学士学位毕业设计河北联合大学轻工学院学士学位毕业设计 5 of highway ZhuangTian period of basic seismic intensity for degrees basic earthquake intensity area According to the code for seismic design of building GB50011 2001 regulation ZhuangTian section design basic earthquake acceleration value is 0 15 g The most important purpose by the ministry of highway engineering design code for seismic design 5 Engineering geology and hydrogeology evaluation 1 the geological structure Yunnan flat lock highway route

beam bridge type bridge arch bridge suspension bridge cable stayed bridge and bridge from safety just apply economic and beautiful four aspects analysis Among them with security and economic oriented At the same time the choice of the form should give full consideration to the construction and maintenance convenience program The past to the function of the bridge structure enough attention now shipping rapid development of the cause of the bridge obstacle clearance often becomes the transport bottlenecks such as nanjing Yangtze river bridge the bridge obstacle clearance is too small leading to high tonnage level ships impassable affect the upper reaches of Yangtze river the development of the city in bridge beautiful depends on the economic and environmental conditions and decide 2
