【摘要】 本文对一种新型的轻型挡土结构－对拉式挡土结构的受力计算进行了研究，提出了在不同荷载情况下的土压力计算，并提出了拉杆受力计算方法。通过与其它计算方法的比较，解决了挡土结构顶部土压力出现负值的问题，证明了该方法是可行的。更多还原

【Abstract】 A careful study is made on the stress calculation of a new kind of light retaining structureopposite pull retaining structure.The earth pressure calculations under different loads are carried out and a calculating method for pull bars′stress is put forward.Comparing with other existing methods,this method can solve the problem of the occurrence of negative values of the earth pressure at the top of the retaining structure,which proves the practicability of the method.更多还原
