Embodiment Construction
[0054] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered by the claims.
[0055] A method for determining the posture of an arbitrary section of a tunnel, comprising calculating the coordinates C (X, Y, Z) of the center of the section and calculating the normal vector n (a, b, c) of the section, specifically including the following steps:
[0056] Step 1: Collect the tunnel section design drawing and the horizontal curve element table and vertical curve element table of the section where the tunnel is located;
[0057] Step 2: Input the stake number sn of the tunnel monitoring section, determine the type of flat curve in the section where the stake number is located, calculate the plane coordinates (x, y) and its slope k according to the corresponding calculation method, and calculate the offset distance between the survey route an...

The invention provides an attitude determining method for a random tunnel section. The attitude determining method for the random tunnel section comprises the steps of calculation of the section central position coordinates C (X, Y, Z) and calculation of the section normal vector n (a, b, c). The attitude determining method for the random tunnel section comprises the steps that according to the information of a tunnel section design drawing, a horizontal curve element table and a vertical curve element table and the like, random stake marks in the tunnel intervals are given, types of horizontal curves of the intervals where the stake marks are located are judged, and plane coordinates (x, y) and a slope k are calculated and are converted to the tunnel section central position coordinates (X, Y); types of vertical curves of the intervals where the given stake marks are located are judged, elevation coordinates z and the gradient i are calculated, and the elevation coordinates Z of the tunnel section central position are calculated according to the tilting height H of a setting-out path and a tunnel section central point; and the section normal vector n (a, b, c) is calculated according to the path slope k and the gradient i. The attitude determining method for the random tunnel section is rigorous in theory, easy to realize, and capable of determining the attitude information ofrandom tunnel sections easily, efficiently and precisely.
Description
technical field [0001] The invention relates to the technical field of tunnel engineering safety monitoring, in particular to a method for determining the posture of an arbitrary section of a tunnel. Background technique [0002] With the continuous development of my country's economy and society, the scale of transportation infrastructure construction has gradually expanded, and the number and mileage of tunnels have gradually increased. The Ministry of Transport issued the "Statistical Bulletin on the Development of the Transportation Industry in 2015". By the end of 2015, the total length of railway tunnels built in my country exceeded 13,038km, road tunnels were 12,684km, and subway lines were 4,238km. It is estimated that by 2020, my country will also plan to build 5,000 tunnels with a total length of more than 18,000km. my country has already become the country with the largest number of tunnels, the longest mileage, the most complex construction and the fastest devel...
