【摘要】：多營(yíng)滑坡位于四川省雅安市雨城區(qū)中部青衣江東岸，根據(jù)現(xiàn)有的資料，在多營(yíng)滑坡形成后，近些年都有變形跡象，居民居住區(qū)域和農(nóng)田處有時(shí)會(huì)有地面裂縫出現(xiàn)，滑坡一旦滑動(dòng)，會(huì)產(chǎn)生較大危害。論文對(duì)三維激光掃描儀應(yīng)用于滑坡穩(wěn)定性研究進(jìn)行了探討取得的主要成果如下： （1）使用Leica HDS8800三維激光掃描儀在多營(yíng)滑坡現(xiàn)場(chǎng)采集三維激光掃描數(shù)據(jù)，并使用Cyclone軟件對(duì)獲取的點(diǎn)云數(shù)據(jù)進(jìn)行了后續(xù)數(shù)據(jù)拼接、點(diǎn)云去噪等數(shù)據(jù)處理，建立了mesh模型，對(duì)輸出的點(diǎn)云數(shù)據(jù)格式轉(zhuǎn)換后在CASS軟件中進(jìn)行二維地形圖的制作，繪制出多營(yíng)滑坡的立面圖、剖面圖和平面圖。 （2）采用FLAD3D軟件進(jìn)行數(shù)值分析，建立三維模型對(duì)多營(yíng)滑坡進(jìn)行數(shù)值模擬，通過(guò)收集野外地質(zhì)鉆探資料獲取多營(yíng)滑坡的巖層特性、物質(zhì)組成，選取巖土力學(xué)參數(shù)，計(jì)算出出滑坡的應(yīng)力應(yīng)變狀態(tài)，，計(jì)算安全系數(shù)進(jìn)行穩(wěn)定性評(píng)價(jià)。 結(jié)合三維激光掃描精確復(fù)現(xiàn)滑坡區(qū)域的宏觀視圖觀測(cè)和數(shù)值分析的方法對(duì)滑坡的穩(wěn)定性分析是有效防止滑坡災(zāi)害的方式，對(duì)多營(yíng)滑坡的預(yù)防和治理有著重要意義。
[Abstract]:Duoying landslide is located in the east bank of Qingyi River in the middle of Yucheng District of Ya'an City, Sichuan Province. According to the existing data, after the formation of Duoying landslide, there have been signs of deformation in recent years. There are sometimes cracks in the ground where residents live and farmland, and landslides slide. This paper discusses the application of 3D laser scanner in landslide stability research, and the main results are as follows: 1) using Leica HDS8800 3D laser scanner to collect 3D laser scanning data at the site of multi-camp landslide. Cyclone software is used to deal with the data such as point cloud data splicing, point cloud denoising and so on, and the mesh model is established. After the point cloud data format is converted, the 2D topographic map is made in the CASS software, and the elevation, section and plane map of the multi-camp landslide are drawn. FLAD3D software is used to carry out numerical analysis, and a three-dimensional model is established for numerical simulation of Duoying landslide. Through collecting field geological drilling data, the rock characteristics and material composition of Duoying landslide are obtained. The stress and strain state of landslide is calculated by selecting the mechanical parameters of rock and soil, and the stability of landslide is evaluated by calculating safety factor. The stability analysis of landslide is an effective way to prevent landslide disaster by using 3D laser scanning to accurately reproduce the macroscopic view observation and numerical analysis of landslide area. It is of great significance for the prevention and treatment of multi-camp landslide.
