路基

To be registered anywhere in the world a saluki has to have a pedigree which can be traced back on paper to the original saluki ancestors in Arabia - indeed each type of saluki can still be identified to its area of origin by its type alone.

不论在世界上任何一个地方，萨路基要获得注册，必须有血统证书，并且该血统证书必须要在书面上追溯到其最初的阿拉伯萨路基祖先。事实上，对每种萨路基，至今仍然能鉴别出这一品种最初的产地。

The soakage effect of rainfall on the roadbed was studied by the movement mechanism of interior water in roadbed.

When rolling the roadbed, the best degree of compaction is 93%~95%. When taking Aeolian sand for preventing the water rising, the Aeolian sand replacement should be set above water table, which should normally be made at 50~80 cm depth of soil base with 15~20 cm thickness of replacement for medium wet subgrade and 20~30 cm for wet subgrade. When using stabilized soil inorganic binder for prevention and control of the frost damage, the thickness of the binder is about 25 cm The mass proportion of cement, coal and Aeolian is about 6:40:54 and lime, fly ash and aeolian is about 14:30:56. Based on these, comparative evaluation for various preventing and curing measures of the Aeolian subgrade was given.

通过对试验数据分析得到了其冻结规律，采用碾压击实法，其最佳压实度度为93%~95%；采用风积砂换填隔水法，风积砂垫层时位置应在地下水位以上，一般应在土基50~80 cm深度处铺筑，换填厚度在中湿路基为15~20 cm，潮湿路基为20~30 cm；采用无机结合料稳定土防止、防治风积土路基道路冻害，厚度均应在25 cm左右，其中水泥、煤渣、风积土的质量比约为6：40：54，石灰、粉煤灰、土三者的质量比为14：30：56，在此基础上，对各种措施的防治效果进行了对比评价。

Against these frost damages, took the measures which were presented against the basic causes for the prevention and curing of the frost damage, for instance, rolling the roadbed, replacing the Aeolian sand and stabilizing the soil of inorganic binder and so on, and did experimental study indoor for every preventing and curing measure. The rule of frost damage has been concluded based on the analysis of experimental data.

针对这些冻害，从其产生的根本原因出发，采取碾压击实路基、风积砂换填、无机结合料稳定土路基等措施对其进行防治，并进行了路基风积土冻结试验、碾压击实试验、风积砂换填试验、水泥煤渣稳定土层和石灰粉煤灰稳定土层试验研究。

Three types of subgrade filling material are selected to analyze the change rule of subgrade resilience modulus under different compaction. Meanwhile PFWD（portable falling wei-ght deflectometer） is combined to integrate this parameter with compaction of construction control index,which brings about the conversion relation between three subgrade filling material and compaction. It can provide reference for pavement design and construction.

选定三种不同类型的路基填料，分析在不同压实度条件下路基回弹模量的变化规律，并结合PFWD检测方法，将设计参数回弹模量与施工控制指标压实度联系起来，得出三种路基填料的回弹模量与压实度的转换关系，可为路面设计与施工提供合理的依据。

And as a result of geothermal field dissymmetry and geometrical dissymmetry of slant slope embankment, the road deformation becomes dissymmetrical too.

由于路基地温的不对称和斜坡路基的几何不对称，引起了路基变形的不对称。

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。

Incorporated with indoor model experiment,field experiment and engineering practice,the mechanism of dynamic consolidation treating subgrade and transmission law of tamped function were analyzed and discussed.

结合室内模型试验、现场试验及工程实践，对采用强夯法处理路基时的加固机理和夯击功能在路基中的传递规律进行了分析和研究，并在此基础上分析了强夯时夯击功能在路基中的影响范围，其研究成果对强夯法的应用具有一定的指导意义。

The original roadbed is soft land base adopt plastic draining off board treatment, most section foundation soil already accomplishes a concretion , namely settlement already is in stable state, the roadbed broadens the settlement there existing difference in the old and new in the roadbed.

原有路基软土地基采用塑料排水板处理，大部分路段地基土已完成固结，即沉降已处于稳定状态，路基拓宽后的新老路基存在差异沉降。

Coffer dams and back berms are often built in the two sides of a roadbed for convenient construction, resulting in obstructing wave but letting tide come into the top of the silt roadbed .

海滩区淤泥长期受周期性的波浪荷载和潮汐荷载作用，在淤泥路基排水固结处理前，为便于施工，一般在两侧填筑围堰，并修建反压护道，波浪作用被阻隔，而潮汐通过排水层进入淤泥路基顶面，对淤泥路基的排水固结过程产生重要影响。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
