The Research Of Measures To Deal With Soft Foundation Based On Yingkou Coastal Industry Base

In Liaoning (Yingkou) Coastal Industry Base is located in northeast coast of China, which is the main distribution area of soft soil,and the geology of the base is very complex. The road construction of the coastal industrial base is facing many problems such as the high cost, the great difficulty of construction, long duration and so on. The main purpose of this study is to handle with the hard problems that the surrounding area of soft foundation in Liaoning (Yingkou) Coastal Industry Base is facing with, find how to reinforce the soft soil subgrade. These projects must ensure that the area under the special conditions of the soil subgrade meet the specifications of quality, as well as the demands of cost-effective, convenient construction, and a reasonable period. After the first phase of construction, we found that it's hard to solve the region's special problems of subgrade soil by using the conventional soft soil treatments. As a result, a new treatment methods is urgent to find out. This paper, after the completion of the geological and hydrological survey to the construction site, raises three preliminary programs of the foundation structure for dealing with the subgrade; Concrete construction technology of each program is settled though the paving of experimental roads; and completes the settlement and stability analysis checking of the Sections after treatment; finally, we raised the most appropriate programs for the foundation soil of the Industry base, and compared them with the traditional programs in economic and technical approach.
