Results demonstrate that climate fluctuations recorded by the two boreholes correspond to the marine oxygen isotope stages. Thick layer of coarser grained fluvial deposits and the third layer of "hard mud" were deposited in the study area during MIS 6, reflecting a cold climate. The sediments became fine-grained and indicate a coastal marsh depositional environment during MIS 5. The second layer of "hard mud" was deposited during MIS 4. Fine-grained coastal marsh deposits dominated in the study area during early MIS 3, while lagoon-beach ridges prevailed during middle and late MIS 3, forming a layer of silt and fine sand in the coastal plain. The MIS 2 strata are composed of a typical sedimentary sequence with coarse grain in the lower section and fine grain in the upper section, i. e. yellowish grey or brownish yellow silt and brownish yellow or dark green "hard mud", respectively.
研究结果显示，两孔记录的古气候波动可与深海氧同位素曲线进行对比：对应于深海氧同位素曲线第6阶段(MIS6)，堆积厚层的河道相粗颗粒沉积及第3硬土层，反映当时气候寒冷；第5阶段(MIS5)，为滨海湖沼沉积，沉积物的颗粒显著变细；第4阶段(MIS4)，本区形成第2硬土层；第3阶段(MIS3)的早期，本区也发育滨海湖沼沉积，中晚期则形成潟湖—砂坝体系，在滨海平原区普遍发育粉、细砂层；第2阶段(MIS2)，地层由下粗上细的沉积序列构成，下部为黄灰、棕黄色粉砂，上部则为棕黄色或暗绿色硬粘土。

So from the aspects of economical and social benefit, it has a lot of advantages. On the other hand CFG pile with long screwy drill pipe inner pump pressure is low noisy and without muddy water pollution; The process of drilling will not lead to vibration and has the capacity to penetrate hard rock layer; Also the construction is of high efficiency.
并且长螺旋钻管内泵压成桩工艺具有低噪音，无泥浆污染；成孔制桩时不产生振动；成孔穿透能力强，可穿透硬土层，诸如沙层、圆砾层和粒径不大于60mm的卵石层；施工效率高等优点，所以该技术在全国推广后，得到了广泛的应用，目前已成为应用较为普遍的地基处理技术。
