VARIABLE APPLICATION FOR THE FORMULA OF APPROACHINGMETHOD SPOT BY SPOT IN ROAD BED LOFTING
Hu Guixian
The approaching method spo t by spot is the w ay g enerally used in measuring the side pile befo re the road bed const ructio n. The approx imate lo cation o f the side pile should be first measured in the cross sectio n map, then i t w ill be approached to the desig ned side pi le spo t by spo t th ro ug h calculatio n. But where the topog raphy i s chang ed during the const ructio n of road bed, the method could not be used directly in the seco nd road bed lof ting f rom the desig n v ariatio n. Thi s a rticle presents details of the va riable a pplicatio n for the fo rmula of approaching method spot by spo t during the changing const ruction co ndi tio n, taking the road bed w o rks f rom K10+ 728. 5 to K11+ 206. 75 of Badaling Ex pressw ay for ex ample. It al so appoints o ut a new rela tio n fo rmula to define the side pile lo cation, and rai ses a new method for the road side lo f ting in the complicated topog ra phic section.

STUDY ON MAIN TECHNICAL ESSENTIALS AND ORGANIZAFION OF WAGON FLOW FOR HEAVY-HAUL RAILWAYS
Zhu Ling
Combined wi th the pratices on the desig n of the Da-Qin and the Shuo-Hua ng rai lw ay lines, the selection of the main technical essentai ls, such as the number o f t rack-line, limi ting g radient, t ractio n mo de, type o f locomotiv es, effectiv e leng th of reception-depar ture t racks and so on fo r the heavy-haul railw ays are studied. Based o n the analy ses concerned w ith the desig n o f traf fic o rgani zatio n mo del, the present o peratio n si tuatio n and the existing problems fo r the Da-Qin rai lw ay, the pa per ex po unds the scheme o f o rg ani za tion of wag on f low s fo r the heav y-haul railw ay and the dev eloping prospect o f the heav y-haul unit t rain. The sug g estio ns are also proposed. They are v aluable as reference fo r giving play to the synthetic effect o f the heavy-haul rai lway , rai sing the t raf fic capaci ty of railw ay and increasing the so cial economic benefi t s.

DESIGN AND CONSTRUCTION ABOUT USING CABLE TO LIFT SIMPLY SUPPORTED BEAM
Liu Yanhua
The autho r int roduced the course of the desig n, calculation and const ruction about using cable to li ft the hig hway simply suppo rted beam, solv ed the pro blem successfully that the beam can 't be li f ted at the same time and can 't be taken it s locatio n o ne time. The autho r t ried to reduce the compression on the tow er a nd deck by means of using stays joining the bo ttom of the two tow ers.
