研究井场为九龙沟内一预探井,由于井场地处斜坡区,为保持场地平整,在前期施工进程中进行了大量的挖填方工程;为保证高填方边坡的稳定性,已在填方区前缘修筑“T”型重力式挡墙。但在后期施工过程中,场区坡体及挡墙等建筑物出现拉张裂缝,变形迹象明显,具有较大危险性。本文根据场区变形迹象分布规律,结合场地地形、建筑物分布及其受影响程度等,对场地进行了分区并详细描述了各区工程地质特征;在此基础上,根据填土特征及原始坡体物质结构特征,对场区变形机理及稳定性影响因素进行了分析;最后采用极限平衡法对各区整体及局部稳定性进行了计算,计算结果为分析场区坡体稳定状况及预测可能造成的工程危害性提供了评价基础。 The well site is a pre-exploration well in Jiulonggou. Since the well site is located in the slope area, a large number of excavation and excavation projects have been carried out in the early stage of construction in order to maintain the site formation. To ensure the stability of the high-fill slope, Fill zone front to build “T ” type gravity retaining wall. However, in the later construction process, cracks and cracks appear in the buildings such as slope bodies and retaining walls in the yard area, with obvious signs of deformation and great danger. In this paper, according to the distribution law of the deformation of the site, combined with the terrain of the site, the distribution of the buildings and the degree of their influence, the site is divided and the geological characteristics of the project are described in detail. Based on the characteristics of the fill and the original slope Material structure characteristics of the field and the deformation mechanism of the field and the influencing factors of stability are analyzed. Finally, the limit equilibrium method is used to calculate the overall and local stability of each area, and the calculation results are used to analyze the stability of the slope in the field and predict the possible engineering Hazard provides the basis for evaluation.
