Subgrade structure, as the main structure of railway construction, should have enough carrying capacity and deformation resistance capacity, can stand repetitive strength of the vehicle load without structural destruction and excessive sedimentation and deformation, meanwhile, it should have preferable penetration resistance capacity and water stability, to reduce water immersion and intenerate effect, therefore maintaining long time stability of the subgrade.

作为铁道建筑主体构筑物的路基结构，应具有足够的承载能力和抗变形能力，能经受车辆荷载的反复作用而不产生结构性破坏和过量的沉降变形，同时还应具有较好的抗渗透性和水稳定性，降低水的浸入及软化作用，保证路基长期处于稳定状态。

Three typical cross section of subgrade has been chosen to test, one of which is near the rail gap. The dynamic characteristic test of subgrade bed including part of subballast and the long-pe

根据各断面在列车荷载作用下的动应力、动变形、振动速度、加速度和累积沉降等实测数据，分析了各影响因素对基床动力特性的影响和不同加固方案及轨缝附近线路的长期沉降变化规律，有以下基本结论：(1)砂土夯实桩与土工格室加固措施能提高基床的承载力，改善基床

随着我国铁路事业的迅速发展，土质路基无砟轨道应用日渐广泛，土质路基上的无砟轨道结构对下部基础的沉降和差异沉降提出了严格要求。

Asphalt Pavement will generate various cracks after go into service, because of the immersion of road surface water, the moisture of the pavement structure layer and the subgrade on the both sides of crack will increase, resulted in lower strength of subgrade and pavement.

随着交通量迅速增加，特别是大吨位车辆行车荷载的作用，路基、路面承受不了超载车辆荷载的作用，加快路面的裂缝产生，大大缩短沥青路面的使用寿命。本文对沥青路面裂缝常见形式和裂缝产生的原因进行了分析，同时也提出了相应的防治措施。

Finally comes a conclusion of this essay that the load of the compounding subgrade increases in a certain degree, the settlement of soft and weak layer becomes relatively even and the maximum settlement correspondingly reduces by such flexible loads like road bank after setting gravel pile in the soft and weak subgrade.

本文最后给出了研究结论：在软弱地基中设置碎石桩后，在路堤等柔性荷载作用下，复合地基的承载力有一定程度的提高；软弱层的沉降比较均匀，最大沉降量相应减小。

Comparison results show that heat pipe work is not continuous but fluctuant in one work cycle about five months,its actual working time is two-thirds of one work cycle,the cooling effect of heat pipe subgrade in winter is obvious,which is good for the contained cool increase of soil body and improves subgrade heat stabilization,there is a decrease for its cooling strength with the increase of horizontal distance,its effective operating radius is 2.25 m,its maximum cooling strength is in evaporation segment in depth direction,which low the thaw sensitivity of permafrost in the seasonal thaw layer about permafrost table.

研究发现，热棒在约为5个月的工作周期内并非连续工作而呈波动式，实际工作时间为工作周期的2/3；热棒路基冬季降温效果明显，有利于路基土体冷储量增加，提高路基热稳定性；热棒在路基中的降温强度，水平方向随距离增大而衰减，有效作用半径为2.25 m，深度方向在热棒蒸发段最大，降低上限附近季节融化层冻土热融敏感性。
