继阳山风电场场址风电机组基坑开挖后,其所揭露的构造形迹在X型节理基础上进一步发展成为断裂.这些断层的性质,既有压扭性,也有张拉性;既有平张,也有逆掩冲;既有压迭性,也有张迭性.不同部位反映了不同的构造时空特征,反映了场区构造严格受区域构造控制.区域内燕山期主应力方向为WN-ES,并伴有左旋剪切应力,喜山期主应力方向为EN-WS,伴有右旋的张拉应力,风电场址区的主要工程地质问题是由于张性断裂,形成不均匀地基以及处于边山构造带的抗滑稳定问题,通过分析研究,有针对性地提出了移位和刻槽换填等处理措施.

@@@@A er foundation excavation of Mount Jiyang wind farm, x-type divisional planes revealed develop into fractures. e properties of fractures include both compressive and tensile, both at and overthrust. Di erent properties re ect di erent tectonization. e eld tectonization strictly controlled by the regional tectonization. e principal stress direction in phase of Yanshan is NW-SE with sinistral shear stress. e principal stress direction Himalayan Epoch is NE-SW with dextral tensile stress. e engineering geological problems are irregular foundation and sliding stability due to the tensile fracture. rough analysis , targeted measures are applied.
