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。

Moreover drilling measures in different strata are pointed out,which are firstly drilling without slurry in part of silty clay layer,secondly adopting double-bottom bailing bit and bore directly and abandoning slurry with impact drilling rig in muddy clay layer,thirdly selecting short screw auger at low speed in gravel layer,finally choosing rock-socketed drilling tube in shaly sand layer.

指出旋挖钻机在不同地层中的钻进措施：部分粉质粘土层中可用清水或干孔钻进，淤泥质粘土层中采用双底捞砂钻头、直接用冲击钻机钻孔弃浆，圆砾层中采用短螺旋钻头低速钻进，泥质砂岩层中采用嵌岩钻筒钻进等措施，保证施工工期满足架梁节点要求。
