The author suggests that the three lithosphere - scale faults, lancangjiang fault, jinshanjiang - ailaoshan fault and axis fault in the middle of the basin, are the main geological structures that control the formation of basin, magmatism and metallogenic congregate district. the anticline structure with an axis of triassic strata and the related fault system within the basin, and gonglang arch - shaped folding structure in the south of the basin are the geological structure controlling the formation of ore fields. junctions of two or more faults with different orientation, interlayer cataclastic structural zone and oxidation - reduction ( redox ) boundary were the favorable position for the formation of ore bodies
認為瀾滄江斷裂、金沙江-哀牢山斷裂及盆地中軸斷裂這三條巖石圈斷裂是主要的控盆-控巖（巖漿巖）構造及礦集區尺度的控礦構造；盆地中以三疊系為軸的背斜構造及相關的斷裂系統、盆地西南緣公郎弧形構造等是礦田尺度的控礦構造；多組斷裂的交叉、層間破碎帶及地層柱中的氧化還原界面是形成礦體的有利部位。 -
In the former, two computing modes of fem are built, aimed at the coupling of variable - profile pylon, curved - axis arch and flexible cable. the software algor feas is used to get the results of dynamic numerical analysis, such as natural vibration frequency, vibration mode, dynamic displacement, dynamic stress, which are compared with the results of shaking table test research to draw to important conclusions. these conclusions provide not only potent basis for the design and construction of nanjing century tower, but also reference for other pylon - cable - arch structures similar to the project
