中英浅基础地基承载力和变形计算方法对比分析

Comparison of calculation method of bearing capacity and deformation of soil for shallow foundation between China Standard and UK standard

中英两国因岩土勘察体系和设计理念不同,造成岩土工程的设计方法也有不同。随着中英两国开展了一系列的能源合作项目,有必要对英国的地基承载力和沉降计算方法有所了解并找出同我国规范的差异。通过分析中英两国在岩土工程设计基准(包括规范体系、设计基本要求、设计等级、设计极限状态)、浅基础的地基承载力及变形计算方法、岩土参数的获取和选用等方面,阐述了中英岩土设计各自的特点和异同之处,为从事与英国建设项目有关的地基承载力和变形评价工作提供了参考依据。

The design methods of geotechnical engineering in China and UK are different due to the differences in the geotechnical investigation systems and design philosophy.With a series of energy cooperation between China and UK,it’s necessary to know the assessment method of ground bearing capacity and deformation and find out differences between China and UK standards.The design basis,including the standards systems,general requirements,design class and limit states,and calculation method of bearing capacity and deformation of soil for shallow foundation,and the determination and selection of geotechnical parameters,are analyzed in order to summarize the characteristics and commonness and discrepancy as specified in China and UK in terms of geotechnical design.The results will support the engineer who works for UK projects in the assessment of the ground bearing capacity and deformation.
