道面地基工后沉降是机场建设岩土工程关键技术问题之一。根据飞机主起落架构型确定基础底面的受力范围和附加应力大小,在此基础上采用《建筑地基基础设计规范》规定的方法计算工后沉降量。计算结果表明,经过置换处理的道面地基工后沉降量满足设计要求。
Road surface subsidence after construction is one of the key technical problems in geotechnical engineering of airport construction. According to the main landing gear configuration of the aircraft to determine the basic bottom of the force range and additional stress on the basis of the use of “foundation code for building foundations” approach to calculate the post-construction settlement. The calculation results show that the post-construction settlement of pavement foundation after the replacement process meets the design requirements.
