the gradual change straight line is a constant height value-H from the end position of the straight line section on the stroke length of the subway running curve section z Constant height value II H in circle passing through circle curve section as starting point qa Or constant height outside the circle II H qi A constant height value H of a straight line from the middle section to the beginning of the straight line section z Gradual change of two points and one line height value connected as terminal pointA straight line (S);
the gradual change curve is a constant height value-H from the end position of a straight line section on the stroke length of the subway running curve section z Constant height value II H in circle passing through circle curve section as starting point qa Or constant height outside the circle II H qi The gradual change curve (S1) is formed by connecting two points with a line height value, wherein the two points are formed by connecting a straight line at the middle section, namely a straight line, and a constant height value reaching the beginning of the straight line section, namely Hz as an end point.
2. An evacuation platform for curved section of subway as claimed in claim 1, wherein said subway has no superelevation in straight section, gradual superelevation in gentle curve section, constant superelevation in circular curve section, and the superelevation value in circular curve section is the highest value of superelevation value in said curve section.
3. An evacuation platform according to claim 2, wherein the constant height within the circle is two H qa Constant height outside the circle II H qi Calculating according to the following formula I and formula II:
H qa ＝H z -B sina formula
H qi ＝H z + B si na formula two
H qa -a constant height value of two within the circle,
H qi -a constant height value of two outside the circle,
hz-a constant height value of one,
b-vehicle half width at the position of the carriage floor surface,
a-vehicle inclination angle due to superelevation.
4. An evacuation platform for curved sections of subway which travels as claimed in claim 1, wherein said gentle curve section is arranged as a transition section (L) in the straight section (Z) and joining the curved section (Q), the transition section (L) being the distance from the transition point of the straight section and the curved section to the straight section extending by the distance of the vehicle.
