Document Type and Number:
WIPO Patent Application WO/2019/140794
Kind Code:
A1
Abstract:
A dimensional analysis-based method for calculating total thrust of shield tunneling comprises: determining a parameter affecting total thrust of tunneling; calculating main control items and dimensionless total thrust; summarizing and listing the calculated main control items and dimensionless total thrust; performing, using linear regression, coefficient identification with respect to the main control items; and obtaining, according to the coefficient identification result relating to the main control items, a calculation model for the total thrust of the tunneling. The method calculates total thrust of an underground tunneling machine rapidly and accurately. The invention follows the principle of dimensional consistency, takes into account the effects of core factors such as geological environment, operating status, and machine structure, and provides an accurate and reliable calculation result. The invention flexibly adjusts a total thrust parameter according to changes in geological conditions, tunneling speed, etc., thereby providing reliable data for designing a power system of a tunneling machine and for setting and real-time adjustment of a thrust parameter during construction.
