Calculation method for determining vehicle meeting field set position in shield long-distance driving tunnel

Abstract

The invention relates to a calculation method for determining a vehicle meeting field set position in a shield long-distance driving tunnel. The calculation method for determining the vehicle meeting field set position in the shield long-distance driving tunnel comprises the first step of collecting and sorting parameters needed by the calculation of the vehicle meeting field set position, the second step of conducting checking calculation on whether alternate transportation of two locomotives meets requirements of actual engineering shield long-distance driving or not according to shield driving and split ring continuous operation conditions, the third step of determining a first set position of the vehicle meeting field in the tunnel according to the shield driving and split ring continuous operation conditions which can be met by one locomotive, and conducting shield driving till the vehicle field meeting condition can not be met by two locomotives, the fourth step of determining a second set position of vehicle field according to the shield continuous operation condition and the vehicle field meeting condition in the situation of the two locomotives, and conducting shield driving till the vehicle field meeting condition can not be met by the two locomotives, and the fifth step of repeating the calculation steps of the fourth step to calculate the third time and even more times of the set position of the vehicle meeting condition till the shield driving is completed. The calculation method for determining the vehicle meeting field set position in the shield long-distance driving tunnel has the advantages that the calculation is simple and convenient, the calculation cost is low, the efficiency is high, and the calculation method for determining the vehicle meeting field set position in the shield long-distance driving tunnel completely adapts to the requirements of fast shield driving.

Description

【Technical field】 [0001] The invention relates to a matching method for shield construction, in particular to a calculation method for determining the location of a meeting yard in a shield long-distance excavation tunnel, and belongs to the technical field of underground construction engineering. 【Background technique】 [0002] Shield technology has been widely used in my country's subway engineering and urban underground space development and utilization. The efficient excavation of shield technology has always been one of the hot issues in the field of underground engineering technology research. In recent years, with the large-scale construction of long shield tunneling projects, long-distance horizontal transportation in tunnels has become a key technical link that restricts the efficient tunneling technology of shield tunneling, and has received extensive attention in the fields of engineering technology and academic research. [0003] Shield construction is similar to...
