In views of the limitations of the existing methods for calculating the pile foundation capacity, a back analysis approach of the m-value is introduced. In order to consider the sensitivity of pile behavior to the m-value,the relationships between the applied horizontal loads at pile head and the corresponding m-value along with the pile stiffness changes are studied. Based on statistics data from the extensive in-situ tests, the back analysis results suggest an exponential expression for the m-value in various soil conditions and horizontal displacements at pile head. This method is capable of providing an accurate m-value in calculating the pile responses under lateral loads.

【摘要】随着中国国际地位的提升,英语作为一门国际通用语言,在我们日常生活中的使用频率越来越高。英语阅读一直在高考英语试卷中占据极大比例,除去作文和听力,剩下的题目基本上都是在考查英语阅读能力。因此,教师在讲授过程中,也应该着重培养学生的阅读理解能力。近些年来,随着社会学、教育学、语言学的发展,很多教育者开始倡导学生主导式课堂,让学生化被动为主动,主动去接触知识、去钻研、去学习知识。从而逐渐形成了一
