Abstract
|
Jump automobile at bridge end in soft clay area is a difficult problem of highway building over the years. The most of highway in our country have this matter because of differential settlement. The way in common use is set up a section between bridge abutment and embankment.In the paper,first we analyze characteristic of settlement and account method about soft clay ground at bridge approach. Value of settlement factor when total settlement is calculated by experimental formula method is discussed. Then,in accordance with settlement characteristic of composite ground with cement-mixed columns that is bearing the act of flexible road,we analyze and select proper account method of roadbed settlement,and discuss key parameter in design.Final,based on the analysis about physical and mechanical characteristic of three kinds of embankment fillings,advantage of light filling opposite stone filling is proved. According to economic accounting,we choose comprehensive manage way which can give consideration to both effect and economy.
