【摘要】：由于地質(zhì)、水文等環(huán)境條件的復(fù)雜性，現(xiàn)代山嶺隧道施工過程面臨諸多的安全風(fēng)險(xiǎn)，充分利用現(xiàn)代物探手段針對(duì)隧道施工開展地質(zhì)超前地質(zhì)預(yù)報(bào)工作，對(duì)于保證施工安全具有重要意義。由于實(shí)際情況的復(fù)雜性，當(dāng)施工過程中遇到復(fù)雜地質(zhì)情況時(shí)，采用綜合超前地質(zhì)預(yù)報(bào)技術(shù)措施往往比單一技術(shù)手段更具工程實(shí)用價(jià)值，因此如何結(jié)合實(shí)際情況針對(duì)不同的超前地質(zhì)預(yù)報(bào)結(jié)果進(jìn)行綜合分析和解釋，對(duì)于實(shí)際工程而言更具實(shí)際意義。 本文以某高速公路隧道施工超前地質(zhì)預(yù)報(bào)為工程背景，在本課題組已有相關(guān)研究工作的基礎(chǔ)上，進(jìn)一步開展基于地震散射場(chǎng)理論GPT技術(shù)的應(yīng)用研究，本文主要研究工作內(nèi)容如下： （1）針對(duì)常用的隧道施工超前地質(zhì)預(yù)報(bào)方法進(jìn)行了總結(jié)和歸納，，探討和分析了目前實(shí)際工程中應(yīng)用較多的隧道施工超前地質(zhì)預(yù)報(bào)技術(shù)特點(diǎn)和應(yīng)用范圍。 （2）從實(shí)際工程的需要出發(fā)，針對(duì)地質(zhì)雷達(dá)法和地震反射波法超前地質(zhì)預(yù)報(bào)的技術(shù)特點(diǎn)、應(yīng)用效果和存在的問題進(jìn)行了闡述和分析；重點(diǎn)介紹了基于地震散射波理論的隧道施工超前地質(zhì)預(yù)報(bào)新技術(shù)GPT的技術(shù)特點(diǎn)和實(shí)施方法，即通過采用6炮12道多次覆蓋和陣列式觀測(cè)方案，以達(dá)到改進(jìn)和完善超前地質(zhì)預(yù)報(bào)技術(shù)的主要目的。 （3）以正在興建的某高速公路隧道施工超前地質(zhì)預(yù)報(bào)項(xiàng)目為工程依托，開展了GPT超前地質(zhì)預(yù)報(bào)新技術(shù)的現(xiàn)場(chǎng)試驗(yàn)和對(duì)比研究，取得了相應(yīng)的應(yīng)用研究成果，通過地質(zhì)雷達(dá)技術(shù)和現(xiàn)場(chǎng)開挖對(duì)比，驗(yàn)證了本文成果的合理性和有效性。
[Abstract]:Due to the complexity of geological, hydrological and other environmental conditions, the construction process of modern mountain tunnel is faced with many safety risks. Because of the complexity of the actual situation, when the construction process encountered complex geological conditions. The technical measures of comprehensive advanced geological prediction are often more practical than the single technical means, so how to analyze and interpret the different geological forecast results in combination with the actual situation. It is more practical for practical engineering. In this paper, based on the engineering background of advanced geological prediction of a highway tunnel construction, based on the related research work of our group, the application of GPT technology based on seismic scattering field theory is further studied. The main contents of this paper are as follows: This paper summarizes and induces the commonly used geological prediction methods for tunnel construction, and discusses and analyzes the technical characteristics and application scope of advanced geological prediction in tunnel construction, which are widely used in practical engineering at present. (2) according to the need of practical engineering, the application effect and existing problems of geological prediction advanced by geological radar method and seismic reflection wave method are expounded and analyzed. This paper mainly introduces the technical characteristics and implementation methods of GPT, a new advanced geological prediction technology for tunnel construction based on seismic scattering wave theory, that is, by adopting 6 guns and 12 channels multiple coverage and array observation scheme. In order to improve and perfect the main purpose of advanced geological prediction technology. Based on the advanced geological forecast project of a highway tunnel under construction, the field test and comparative study of the new advanced geological forecast technology of GPT are carried out. The corresponding application research results are obtained, and the rationality and validity of this paper are verified by the comparison of ground penetrating radar technology and field excavation.
