These two parameters are nowadays called the modulus of compressibility . 這兩種參數(shù)現(xiàn)被稱為壓縮模量。
6 . using present theoretics , the author puts forward the theory of calculating the value of n by the modified value of modulus of compressibility a : . the value of k is 1 . 1 - 1 . 2 in the engineering of nanjing - qidong railway 最后,在現(xiàn)有的理論基礎(chǔ)上,借助于靜載試驗,提出了采用地基土壓縮模量的k值修正計算樁土應(yīng)力比n值的方法,并根據(jù)寧啟鐵路工程實例取k值為1 . 1 1 . 2 。
By an engineering example , the paper makes analysis of the problems existing in the assessment of a clayey ground , proposes that it would be appropriate to adopt manifold methods for the investigation and assessment of the clayey ground , in case of the standard value of bearing capacity does not coordinate with the value of modulus of compressibility , it is suggested that stratification and assessment should be made according to the modulus of compressibility , and checking computation of settlement should be conducted also 該文通過某工程實例,對粘性土地基評價中存在的問題進行了分析,認為采用多種方法對粘性土地基進行勘察和評價為宜,當承載力標準值與壓縮模量不協(xié)調(diào)時,建議按壓縮模量進行分層和評價,并且進行沉降量驗算。
Secondly , analytical solution is developed for one - dimensional non - homogeneous consolidation of one - layer soil and double - layered soil respectively based on the assumption that the modulus of compressibility of soil varying linearly along depth . furthermore , the semi - analytical solution for one - dimensional consolidation problem of layered non - homogeneous soft clay stratum is presented and programmed . by using the analytical and semi - analytical solutions , the one - dimensional non - homogeneous consolidation behavior of one - layer soil and that of multi - layered soil are investigated in detail 其次,分別得到了土體壓縮模量隨深度線性變化的單層和雙層非均質(zhì)地基一維固結(jié)解析解,以及滲透系數(shù)和壓縮系數(shù)隨深度任意變化的成層非均質(zhì)地基一維固結(jié)半解析解及其計算程序,并以滲透系數(shù)和壓縮系數(shù)是深度的多項式函數(shù)的非均質(zhì)地基為例對單層、多層非均質(zhì)地基的一維固結(jié)性狀進行了詳細研究。
Base on the finite element method , the major factors that affect the work behavior of self - expanded pile are studied , these major factors include the modulus of compressibility of pile side soil , bearing stratum soil and substratum soil ; the ratio of length and radius of pile ; the ratio of expanded body ' s radius and pile ' s radius ; the depth into bearing stratum of pile end ; load value and so on 然后通過有限元法分析了影響自擴樁工作性狀的主要因素,研究了樁周土、持力層和下臥層土的性質(zhì)、長徑比、擴徑比、樁端進入持力層深度、荷載大小等因素對自擴樁荷載傳遞特性的影響。
