摘要
西部大开发,交通是关键。公路建设已成为西部开发的首要任务。四川省是西南地区经济发展的龙头,108国道是我国中西部地区纵贯南北的主干线,是西部经济发展的大动脉,而108国道广元北段地处低山地段,边坡失稳现象较常见。
     经过近百年的发展,边坡的稳定性研究经历了一个由静态到动态、确定性到非确定性、二维到三维、均质各向同性到非均质各向异性的发展历程。本文基于前人的研究成果,作者以108国道广元北段的典型岩质边坡为背景,运用现已逐步形成的地质原型研究→成因机制分析→稳定性分析计算→工程地质评价为主体的系统工程地质分析方法对其进行研究。
     本文在现场调研和资料收集的基础上,对广北段典型边坡的变形破坏机制和稳定性评价进行了详尽的研究。其主要内容包括:①通过详细研究该区岩土体的基本类型及特征、边坡结构及其组合类型,并提出合理的治理措施,本研究区边坡结构类型主要为顺向、反向和切向三大类型。②进行公路边坡的稳定性研究,首先必须搞清边坡的变形破坏机制模式。通过对典型边坡的物理模拟试验,研究发现K23+850处中倾顺向岩质边坡变形破坏形式为滑移—拉裂型,而K47+750处的陡倾内反向岩质边坡的变形破坏形式为弯曲—拉裂型。③其次是建立合理的地质模型,对边坡进行定性及定量评价。通过对典型边坡的HSMR稳定性分级及极限平衡法定量评价,研究发现K23+850及K28+500处边坡的稳定状况都很差,需加大治理力度。④通过对典型边坡K23+850和K47+750的离散元数值模拟研究,再现和预测了该边坡的变形破坏全过程,对治理该类型边坡提供了可靠的地质依据。
Traffic is very important in the west development project, so the highway construction become its first mission. As the lead of southwest economy, Sichuan plays a very important role in the developing. 108 Highway is the South and North mainline to run through middle-west area in my country, and is the main artery of west area economy developing. Guangyuan north section of 108 National Highway lies in low mountains, and its slope often is unstable.
    By a hundred of years development, the study on slope stability has experienced such progression: From statistic to dynamic, confirming to unconfirming, double dimensions to three-dimension and from isotropy to anisotropy. Based on current research fruits, for example 108 Highway's typical rock slope, the writer adopts the system engineering geology analysis method that become already and gradually with the geology prototype research, analyzing the mechanism cause, stability analysis calculation and engineering geology evaluation to research them.
    With investigation on the spot and data collection, the context proceeds to the typical slope in details of research about transform and the failure mechanism and evaluation with the stability. Its main contents includes:(1)Through studying in details the basic type and characteristic, slope constructions and its combination types of the area's rock soil, and putting forward to manage the measure reasonable, the context finds the result that this area's slope construction type is main dip slope, scarp slope and transverse slope.(2)Before studied the stability of the highway slope, it must be knowing the transform and the failure mechanism mode. Through imitated to experiment to the physics of the typical model slopes, it can be found that the K23+850's dip slope is belong to creep-sliding and fracturing, that the K47+750's scarp slope is belong to bending and fracturing, (3)it is a effective method by establishing the reasonable geology model, and proceed to study with evaluation of determine the nature and fix quantifying. With HSMR stability classification and extreme limit evaluation, K23+850 and K28+500's slope stability are very bad. They need the enlargement manayes dint degree.(4)By DEM researching the typical K23+850 and K47+750's slope, it reappears and predicts whole process of the slope transform and the failure. The process provides the dependable geology gist to manage the typical slope.
