The main points of view are:1.Since the liberation,tremendous achiêvements in railwayconstruction have been attained;the scheme of new line layout was offoresight and sagacity.Further economical principle should be executed in the engineeringworks of tomorrow.2.The investment used in strengthening the motive power and promotingthe level of technology is far more worthwhile than that used in excessivecivil engineering work.Specific problems are as follows:1.The train speed and the minimum radius of curvature standards ofdifferent classes regulated in the engineering specification appear too lowfor the plain districts,but they are too high for the complicatedmountainous regions.2.The 16 stage classification of radii of curvature in specificationis uneconomical.3.Too flat ruling grades was adopted in some of the trank lines inthe mountainous districts.It results in excessive construction work,expensive investment,delayed date of completion of the railways.In fact,the volume of traffic does not reguire,such flat slopes as they were made.4.Still steeper grades are suggested on the lines accross the parallelmountain ranges and rivers along the boundary between Tibet and otherprovinces,as well as on the industrial tracks in difficult topographic conditions.

This paper discusses the criteria and principle for minimum radius of curve and the transition curve for railway track when running 160kin per hour.In view of satisfaction for safety of operation, ride comfort and economic advantages, according to theoretical analysis, experiments and our actual operational conditions, the paper puts forward the maximum allowable superelevation, the allowable cant deficiency and the allowable excess cant. Three formulas for calculation of minimum radius of curve for satisfying different requirements are also described, by which the design criteria of minimum radius of curve for 160 km/h railway track is to te determined.Based on theoretical analysis and experiments at the different shape of transition curve, this paper proves that the cubic parabola transition curve can satisfy the operational demand when the maximnm speed of train reaches 160km/h. But adopting the half-wave sine curve can offer a better operational conditions of the train. In this paper the main parameter of length of transition curve and the formula for calculation of minimum length are put forward as well.

本文研究了我国时速160公里铁路最小曲线半径与缓和曲线的设计原则和标准。关于最小曲线半径:从满足列车运行安全、乘客舒适和经济合理的要求出发,根据理论分析、试验资料和我国铁路运营情况,提出了曲线最大允许超高、欠超高和过超高的推荐值。同时,提出了三个满足不同条件的最小曲线半径计算公式。还根据客运专用线、客货混运线和新、旧线的不同特点,推荐了我国时速160公里铁路最小曲线半径的设计标准。关于缓和曲线:对不同线形缓和曲线的理论分析和试验实测资料证明,对于最高时速160公里的铁路,继续采用三次抛物线形缓和曲线是能满足运行要求的,采用半波正弦形缓和曲线能创造更好的运行条件。并提出决定缓和曲线长度的主要参数(β)及(ω)值及最小长度的计算公式。
