The lithologic characters changed from fluviolacustrine sandstone to aeolian Red Clay with thin interval of greyish-white sand layers at the depth of 602 m. It can be inferred from the rock strata and age that the development age of aeolian sequence in Lanzhou area was 7 Ma at least, which is in accordance with the bottom age (7~8 Ma) of the aeolian sequence of the eastern and central Loess Plateau, suggesting that their accumulation processes are unitary.

皋兰山剖面深度602 m处出现由河湖相砂岩向以风成红粘土为主常夹有薄层砂岩的地层转变，通过岩性地层及年代的推断，兰州地区的风尘序列堆积发育的年代至少为7 Ma，与黄土高原风尘序列堆积底界8～7 Ma基本一致，说明了兰州地区与黄土高原在风尘序列堆积过程中具有统一性。

Because of a high groundwater level and a strong erosion action, the coal formed in a low peat swamp is great in gelatification index and in groundwa ter index, which are in a negative correlation to the ratio of clean coal recove ry. While for the high peat swamp, IG and IGW are small, corresponding to a high ratio of clean coal recovery.

低位泥炭沼泽由于潜水位较高，水流对泥炭沼泽表面的改造和冲刷作用较强，形成的煤层具有较高的凝胶化指数和地下水流动指数，并且与精煤产率呈负相关，煤中粘土矿物和黄铁矿难以洗选；高位泥炭沼泽形成的煤层具有较低的凝胶化指数和地下水流动指数，泥炭积累速度较快，其精煤的产率较高。

In the paper, we adopt the analytical method concluding the theoretical research and experimental research to create the P-Y curve calculation model that is described by a series of geotechnic parameters such as the unconfined compressive strength, natural gravity and the compression coefficient in the shallow layer of the clay soil . The calculation example indicates that the calculation value of the pile moment of flexure of the body and the peak displacement agree with the measured value.
