Project Geological Conditions
3.2.1风电场址区域内虽有众多的宽深冲沟切割，山坡多为25~40度局部呈陡坡但山顶平缓，多呈近南北向或北东向的梁状山延伸，顶部高程多在500m左右，向两侧缓倾，梁顶宽一般40~100m，遇山包可展宽。局部可见基岩露头，无崩塌、滑坡等不良地质现象分布，亦未发现有延伸长大的缓倾角结构面发育，山体整体稳定性较好。
3.2.1 There are many gully cuttings in location of the wind farm and most of slope are 25~40 degrees while the peak is quite flat, extending from the South to the East or from the North to the East along mountain ridge. The top altitude is about 500m with both sides inclining slightly and the width of top ridge is 40~100m. Partial bedrock appears and no collapsing or landslide, etc. will be distributed and no collapse, landslide distribution or no long, bid or slightly inclined structural surface development, the integrity of plant location is quite well.
3.2.2风电场址地基主要为花岗岩（个别为花岗闪长岩和大理岩）由于长期的风化作用按风化程度在弱风化的基岩上部尚可分出强风化带和全风化带。
3.2.2 The main foundation of wind farm is granite (some places are granodiorites and marbles), dividing heavily-weathered belt and completely weathered belt on weakly weathered belt according to weathered degree due to long-term weathered process.
（1）全风化花岗岩：组成岩石的矿物多已蚀变，长石蚀变为高岭土，岩石结构已遭破坏，强度极大降低，厚度较大时易于变形，且底界面高低起伏，可能存在不均匀沉陷，一般不宜选做风机的天然地基。建议承载力180~300KPa，变形模量80~200MPa。
（1）Completely weathered belt granite: Minerals of rock have almost been corroded; feldspar has been corroded into kaolin and the structure of rock has been damaged so the intensity decreases enormously. When thickness increases, deformation will occurs and the bottom is fluctuated which may cause uneven settlement. Usually, we will not select this kind of granite as natural foundation. The suggested bearing capacity is 180~300 KPa and the deformation modulus is 80~200MPa.
（2）强风化花岗岩：由于风化和构造裂隙发育，岩石较为破碎，裂隙面多已风化蚀变并有铁锰质渲染，强度明显降低，强风化带下部与弱风化带过度段强度有所提高。建议饱和抗压强度为20~30MPa。
（2）Heavily-weathered belt granite: The rock is crushed and most of fracture surface is corroded with the ferric manganese rendering due to weathered influence and development of structural fissure; the intensity decreases obviously. The intensity of transitional reach between the lower part of weathered belt and the weakly-weathered belt increases relatively. The suggested compression strength is 20~30MPa.
（3）弱风化花岗岩：岩石坚硬虽有裂隙切割但多为闭合状，建议饱和抗压强度为50~60MPa。
（3）Weakly-weathered belt granite: The rock in closing status is very hard through there is fissure cutting on it, the suggested compression strength is 50~60MPa.
由钻孔揭露可知上述风化分带及地基岩体的组成各处均有不同，具体表现为：
The drilling will disclose weathered belt and bedrock mentioned above are different, and the detailed findings are as following:
（1）风化厚度分布各地不一，同一地点山梁顶部较厚两侧较薄。
（1）The distribution of weathered thickness is uneven; The peak of mountain ridge is thicker and both sides are thinner at the same place.
（2）全、强风化带分布常有缺失，即全风化岩石直接置于弱风化基岩上，其间无强风化岩石或强风化岩石上部为坡积土而无全风化岩石分布。
（2）Usually, there are lacks in completely weathered belt and heavily-weathered belt, that is heavily-weathered rock is directly located on weakly-weathered bedrock, and the upper parts of non-heavily weathered rock or weakly-weathered bedrock are the slope crushed earth and no completely weathered rock distribution could be found there.
（3）由于局部有断层或裂隙密集带分布沿构造部位风化深度将加深。
ZK1～ZK7钻孔的地质柱状图见图3-1～3-7。物理力学性质指标建议值见表3-2。
（3）The weathered depths of local faultage or intensive fissure zone deepen along structural part.
ZK1～ZK7 are geological column graphs of drilling, referring to 3-1～3-7. The index suggestion on physical and mechanical property refers to Table 3-2.
