国家高速公路包头至茂名线(G65w)边坡为黄土边坡,边坡受地下水位影响较大,稳定性差,治理难度大。本文主要介绍了边坡所处的基本工程概况,描述了土层的分布,以及详细的监测布置方案。无线采集传输系统采集数据并进行整理分析,结果表明:坡体内地下水位下降,加速了边坡的蠕滑发生,边坡的深部水平位移发生较大的偏移,对边坡的稳定性产生了较大的影响;边坡深部水平位移的偏移量在允许变形范围之内且符合V型曲线规律,表明边坡目前处于稳定状态。水是影响边坡稳定性的重要因素,后期要加强对地下水位的监测以及做好边坡防排水措施。
The national highway Baotou-Maoming Line (G65w) slope is a loess slope, and the slope is greatly affected by the groundwater level, which has poor stability and difficult management. This paper mainly introduces the basic engineering of the slope, describes the distribution of the soil, and detailed monitoring arrangement. Wireless acquisition and transmission system to collect data and organize analysis, the results show that: the decline of groundwater level within the slope accelerated the creep of the slope, the deep horizontal displacement of the slope occurred a large offset, resulting in the stability of the slope The offset of horizontal displacement of deep slope is within the allowable deformation range and complies with the V-curve law, indicating that the slope is in a stable state at present. Water is an important factor that affects the stability of the slope. Later, it is necessary to strengthen the monitoring of the groundwater level and prevent and treat the slope.
