Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0031] Such as figure 1 As shown, the embodiment of the present invention provides a method for evaluating and predicting the quality of tunnel smooth surface blasting, including the following steps:

[0032] In step 101 , obtaining evaluation indicators: using expert scoring method and AHP respectively to obtain a set of index sets, and taking the intersection of the two sets of index sets as the evaluation index. As shown in Table 1, the factors affecting the quality of smooth blasting mainly include the following five categories: geological factors, explosive parameters, blast hol...

Abstract

The invention relates to a channel smooth blasting quality evaluation prediction method, comprising the following steps of 1, obtaining evaluation indexes; 2, obtaining an actual measurement evaluation index value of a section to be evaluated, and adopting a variable coefficient method and an analytic hierarchy process to obtain the comprehensive weight of each evaluation index for the total evaluation; 3, performing evaluation prediction on the smooth blasting quality by respectively using a conventional weighting method and a projection pursuit method and obtaining the comprehensive evaluation result of the smooth blasting quality of the section to be evaluated according to the evaluation prediction result obtained according to each method. Compared with the prior art, the channel smooth blasting quality evaluation prediction method has the advantages of convenience in operation, strong systematization, high practicability and the like.

Description

technical field [0001] The invention relates to tunnel smooth surface blasting, in particular to a method for evaluating and predicting the quality of tunnel smooth surface blasting. Background technique [0002] With the rapid development of the national economy and the continuous advancement of urbanization, my country has built a large number of roads, railways and urban subway tunnels, and has become the country with the most tunnels and underground projects, the most complex and the fastest growing in the world. [0003] For blasting evaluation indicators, domestic and foreign scholars have proposed many indicators for each link, including qualitative evaluation indicators and quantitative evaluation indicators. Qualitative indicators include economic benefits, stability of surrounding rock, cracking of surrounding rock retaining hole wall, etc.; there are many quantitative indicators, such as: overbreak, underbreak, blasthole utilization rate, average linear overbreak,...
