The main results of the study are obtained as follows:1 In order to analyze and study the physical and mechanical characteristics of Lianyungang marine soft clay deeply, large numbers of basic mechanical characteristics tests and tri-axial shear tests are completed.2 In order to investigate the loaded and failure characteristics of the cement-soil, the cement-soils for the different ratio and different cure time are studied in the laboratory, and their unconfined compression tests and tri-axial shear tests are performed.3 Based on the solution of one-dimension consolidation, the one-dimension consolidation of the double-layered foundation is solved for two-grade loading in virtue of transcendental equation; Simultaneously, the one-dimension consolidation of the double-layered foundation is solved by means of Laplace transform for two-grade loading, and Stehfest numerical transform is applied in Laplace's inverse transformation; Furthermore, according to the practical foundation shapes, the consolidation models of the soil between piles and the substratum are built and solved respectively.4 The effect of each parameters on the consolidation of the double-layered foundation is discussed, and the solution of load transfer method for double-layered foundation is applied in A1-A4 section of Lian-Xu expressway. The results of calculating settlement of the double-layered consolidation theory are basic agreement with the measuring settlement results.

取得了以下几方面的研究成果：1针对连云港海相软土进行一维固结和三轴剪切试验，深入分析连云港海相软土的物理力学特性。2模拟水泥土搅拌桩施工，在室内制备不同配比、不同龄期的水泥土试样，并进行无侧限抗压试验和三轴剪切试验，揭示水泥土的受力特性及破坏特性。3运用超越方程，以双层地基一维固结解析解为基础，推导出二级加荷条件下双层地基的固结解析解；同时，通过荷载传递法并借助Laplace变换对双层地基的固结问题进行了数值求解；此外，根据实际的地基结构，建立了桩间土和下卧层的固结模型并分别进行求解分析。4分析探讨了双层地基中各参数对双层地基固结的影响程度，并运用荷载传递法的解答计算了连-徐高速公路A1-A4标水泥土搅拌桩处理段的六个断面，计算结果与实测数据有较好的一致性。

Robert had a prim bed-room, and an uncompromising dressing-room allotted to him in the square house, and he woke every morning upon a metallic spring mattress which always gave him the idea of sleeping upon some musical instrument, to see the sun glaring in upon him through the square white blinds, and lighting up the two lacquered urns which adorned the foot of his blue iron bedstead, until they blazed like two tiny brazen lamps of the Roman period.

在那方方正正的大厦里，罗伯特占有了一间整洁的卧室和一间毫不含糊的化妆室；每天早晨他在一个金属弹簧垫子上醒来（这垫子始终给他睡在乐器上的感觉），眼看着太阳透过方方的白色遮帘照射进来，照亮了装饰那蓝色铁床脚的两个红漆小壶，光辉灿烂，活象是古罗马时期的两个小小的黄铜灯。

That the location of the airport帕希姆happens to be in the center of Europe, from Hamburg, 120 km, Berlin 160 km, between the two major German cities have a sea port of iron supply and rail systems, but there is no air transport hub, Pa Fahim stop at the airport between the two cities, while Hamburg is Europe's second largest port, and the Baltic port of Rostock, Wismar, Lübeck circle at the airport, 100 km range, have a direct rail link, the multimodal transport is that it combines the advantages of.

庞玉良认为帕希姆机场的所在位置刚好是在欧洲中心，距汉堡120公里，柏林160公里，两个主要德国城市之间都有海、铁的货源的港口与铁路系统，但没有空运枢纽，帕希姆机场罢处于两城市之间，而汉堡又是欧洲第二大港口，而波罗的海港口罗斯托克、维斯玛、吕贝克在机场圈100公里范围之内，有铁路直接联系，这种多式联运结合是它的优势。

As soon as the two of them emerged from the dense forest, they saw two iron-gray horse-like animals with long pointed ears, tied to a tree.

It was as expansive as all the other rooms in the sprawling apartment-spacious enough for a washing machine, two tubs, an ironing table, and two folding tables-and she nibbled on the cherries sunk in the bottom of her glass while she sat, disappointed that the party had not been as exciting as those in the movies.

洗衣房就像这座豪宅的每一个房间那么宽敞，宽敞得足够放下一台洗衣间，两个浴盆，一个熨衣桌和两张可折叠的餐台，她坐下的时候，把杯底的樱桃放在口里慢慢咀嚼，她感到很失望，这个派对并不像电影里那么有趣。
