路堤

The results indicate the basic reasons of the soil erosion are plenty of discarding soil of cut slope and the increasing discarding soil by kinds of diseases of cut slope later not utilized by the embankment, moreover, the soil have to be borrowed to build the embankment, together with the ruleless of the places of borrowing soil and the fields of discarding soil.

结果表明，引起水土流失的根本原因在于路堑开挖的大量弃方，以及随后路堑边坡的各种病害造成新增膨胀土弃方不能为路堤施工所利用，而路堤填筑又需大量借土，加之借、弃土作业不规范等。

Test results are as follows: Ballastless track structures can effectively improve the dynamic action of train loads on subgrade beds, the measured stresses and acceleration rates are far smaller than those measured with ballasted track structures; axle loads have remarkable influence on dynamic stresses of ballastless track subgrades and have some influence on acceleration responses; speeds of either motor car units or freight trains all have limited effect on dynamic embankment responses; after attenuating over 3 meters high embankment, neither dynamic stresses nor acceleration rates are influential to net cushions at the bottom of column-net structure subgrades

结果表明：采用无砟轨道结构可以有效改善列车荷载对路基基床的动力作用，测得的动应力与加速度值均远小于有砟轨道结构测得的值；列车轴重对无砟轨道路基的动应力影响明显，对加速度响应也有一定影响；无论是动车组还是货物列车，其运行速度对路堤部分的动响应影响均有限；动应力与加速度经3 m 高的路堤后衰减，对桩网结构路基下部的网垫层已基本无影响。

The data from stress box indicate that the observed values usually are smaller than the theoretical ones, and the relationship between the vertical or lateral stress and the fill soil thickness can be described in a power function curve: a- a hb. The fact that the soil stress is bigger in the portion adjacent to the central part of gully and becomes smaller in the portion close to the side illustrates that the gully has an apparent unburdening effect. From the monitoring results of the settlement deformation during and after constructingperiod, the study conducts statistical system analysis and evaluation on the change of settlement with time.
