First this paper presents two-way seepage consolidation solutions of sand-wall ground, based on the assumption of equal strain boundary conditions. Second, comparisons of the solutions and Barons axisymmetric consolidation theoretical solutions are conducted to find an equivalent and matching method for plane strain analyses and axisymmetric analyses of sand-drained ground.

为了能用平面应变有限元来分析砂井地基，本文首先推导出了砂墙地基(砂井地基在平面应变条件下的表现形式)双向渗流等应变固结理论解，然后将此解与巴隆轴对称固结理论解相比较，得到砂井地基平面应变情况和轴对称情况之间的等效公式。

Through the star communication network of VSAT Ku wave band was set up and linked with distance-controlled telephone network at the base, so as to realize the free communication between production unit field and management department at base, at same time, by using the information system of exploration production. it is realized that the specific data processing such as log profile along with drilling well, well logging curves, playback of log second data, real lime data of log instrument, and oil-testing data, geophysical data as well as web releasing function, with the geological data, the daily report of drilling well and oil-testing released onsite together, the dynamic information platform of exploration management has been established, which provides leaders at various level, research personnel and managers with an integrated, abundant data, dynamic information platform along with drilling.

通过建立VSAT Ku波段星状通讯网络，并将其与基地程控电话网络相连，一方面实现了野外生产单位与基地通讯的畅通；另一方面，应用勘探生产信息系统实现随钻录井剖面图、测井曲线、录井秒数据回放、录井仪实时数据及试油、物探资料等专业数据的处理及Web发布功能，与现场生产传输系统发布的地质、钻井、试油日报共同作为勘探动态管理信息平台，为基地各级领导、研究人员、管理人员提供了一个集成的、具有丰富资料的井场随钻动态信息平台。
