【摘要】：采用模型試驗(yàn)是研究滑坡及其抗滑結(jié)構(gòu)的一種有效方法,紅外熱像儀在滑坡模型試驗(yàn)中的應(yīng)用是基于紅外檢測和熱成像原理,利用紅外熱像儀對(duì)滑坡模型抗滑樁區(qū)域坡表溫度進(jìn)行有效、準(zhǔn)確、實(shí)時(shí)地檢測并記錄,有助于分析滑坡破壞過程中抗滑樁所在區(qū)域溫度場的變化規(guī)律,從能量的角度對(duì)抗滑樁土拱效應(yīng)進(jìn)行研究。試驗(yàn)結(jié)果揭示了滑坡抗滑樁區(qū)域溫度場的分布規(guī)律,從溫度場方面證實(shí)了土拱效應(yīng)的存在,并揭示了土拱形成過程及其機(jī)制;抗滑樁有效地阻止了滑坡推力向樁前發(fā)展,發(fā)揮了抗滑效果;滑坡發(fā)生過程中巖土體應(yīng)力場、位移場和能量變化是息息相關(guān)的。紅外熱成像技術(shù)的應(yīng)用為抗滑樁土拱效應(yīng)的研究提供了一種新的研究方法,使得從能量變化的角度研究抗滑樁等防治結(jié)構(gòu)作用機(jī)制成為可能,其可行性和可靠性在模型試驗(yàn)中得到了驗(yàn)證。
[Abstract]:Using model test is an effective method to study landslide and its anti-slide structure. The application of infrared thermal imager in landslide model test is based on the principle of infrared detection and thermal imaging. The infrared thermal imager is used to detect and record the slope surface temperature of the landslide model anti-slide pile area effectively, accurately and in real time, which is helpful to analyze the variation law of the temperature field in the area where the anti-slide pile is located in the process of landslide failure. To study the effect of resisting sliding pile and soil arch from the angle of energy. The experimental results reveal the distribution law of temperature field in the landslide anti-slide pile area, confirm the existence of soil arch effect from the aspect of temperature field, and reveal the formation process and mechanism of soil arch, and the anti-slide pile effectively prevents the landslide thrust from developing to the pile front. The stress field, displacement field and energy change of rock and soil are closely related to the occurrence of landslide. The application of infrared thermal imaging provides a new research method for the study of soil arch effect of anti-slide pile, which makes it possible to study the mechanism of anti-slide pile and other prevention structures from the angle of energy change. Its feasibility and reliability are verified in the model test.
