基于可拓学理论对港区软基处理的沉降分析

Settlement Analysis of Processing on Soft Foundation in Port Based on the Extension

软土地基工程建设施工中,沉降分析是最关键的问题之一。基于可拓学理论对软基进行了沉降分析,综合考虑表层沉降、分层沉降、孔隙水压力、地下水位、倾向变形五个监测数据,在物元模型的基础上,构建了港区软基处理的沉降分析模型,形成了监测体系和实时沉降分析;对监测数据进行了指标归一化、无量纲化预处理;采用VB语言自主开发了相关程序,并将其应用于实际工程,验证理论与程序的正确性,有效提高了软基加固工程的施工效率。克服了传统理论模型对软土地基进行沉降预测时遇到的隐层数和样本数量难确定等问题,实时采用监测数据来进行沉降分析,具有全面性和实效性。

During the construction of soil foundation engineering in soft soils, settlement analysis is one of the most critical issues. The settlement of soft foundation was analysised based on the extension theory, which taken five monitoring data including the surface settlement, layered settlement, pore water pressure, underground water level and the deformation tendency into consideration. On the bases of matter element model, the settlement analy- sis model of used for treatment of harbor soft base was built, forming a monitoring system and a real - time settle- ment analysis; Monitoring data are normalized, the index dimensionless pretreatment; using VB language devel- oped procedures, and applied to the actual engineering, verification of the correctness of the theory and program, effectively improve the efficiency of construction for soft base reinforcement engineering. To overcome the problem of hidden layers and the number of samples encountered in traditional theory model of the settlement prediction of soft soil foundation is difficult to determine, in real time using monitoring data to analysis the settlement, with the o- verall and effectiveness.
