Ground Improvement Using Piled Embankments and Its Design Methods

With the development of society and economic, China has come into a fast period of high speed railway construction. The piled embankment system is one kind of ground improvement. The calculation methods of piled embankments are introduced in this paper from such three aspects as load transfer and distribution, reinforced geosynthetic tension and embankment stability. The different codes of British, German and China are adopted to calculate the soil arching effect respectively. The computation results from different codes indicate that the deviation of results is a little biggish due to the difference of hypothesis about soil arching effect, calculation of load between pile reinforced bedding and reinforced geosynthetic tension and so on. The problems of existing methods should be investigated systematically according to engineering cases.
