| 山体滑坡对下方建筑物和人员的安全会产生影响，因此需要进行有效的勘察工作，然而，传统方法在时间和空间上有一定的限制，无法对滑坡区域内的地质条件进行精确测量。为解决这个问题，本文提出一种基于多道瞬态面波的滑坡区域勘查方法，专门应用于复杂地质条件的研究。本研究以江宁区小东山地区为勘察区域，标记出了 4组滑坡隐患区域，并对其地质条件和地理特征进行了分析，并根据分析结果，制定相应的勘查方案。其中，破坏系数和稳定系数被用作判别条件，采用极限平衡法来演示滑坡作用力的运动形式。同时，通过确定土层探测频率与深度的关系，利用多道瞬态面波技术来捕捉介质性质。基于地质成因条件，设定了评价指标，用于确定不同区域内的滑坡类型，以实现对区域内土层地质的勘查。研究结果表明，在本文提出的方法的应用下，能够对不同工况下的边坡稳定状态进行划分，并获取不同区域内土层垂直和水平渗透性的信息，从而判断滑坡发生的可能性。 |

| Landslides can have an impact on the safety of buildings and people below. Therefore, effective in-vestigation work is needed. However, traditional methods have certain limitations in time and space and cannot accu-rately measure the geological conditions in the landslide area. To solve this problem, this paper proposes a landslide area exploration method based on multiple transient surface waves, which is specifically applied to the study of com-plex geological conditions. This study took the Xiaodongshan area in Jiangning District as the investigation area,marked out four groups of landslide hazard areas, analyzed their geological conditions and geographical features, andformulated corresponding investigation plans based on the analysis results. Among them, the failure coefficient andstability coefficient are used as discrimination conditions, and the limit equilibrium method is adopted to demon-strate the motion form of the landslide force. Meanwhile, by determining the relationship between the detection fre-quency and depth of soil layers, the multi-channel transient surface wave technology is utilized to capture the prop-erties of the medium. Based on the geological formation conditions, evaluation indicators were set to determine thetypes of landslides in different regions, so as to achieve the geological exploration of soil layers within the regions.The research results show that under the application of the method proposed in this paper, the stability state of theslope under different working conditions can be divided, and the information on the vertical and horizontal perme-ability of the soil layer in different areas can be obtained, thereby judging the possibility of landslide occurrence. |
