Abstract : in this paper ， the problems in collecting data of earth pressure are discussed on the basis of some real projects according to the author ， the present way ， in which earth pressure data are calculated completely from classics theory ， is not practical a nonlinear method of row pile design ， in which the cooperative action of ring beam are taken into account and the lateral pressure is calculated on the basis of the pressure of displacement earth are proposed
文摘:本文從實例著手，分析了在土壓力取值上存在的問題，目前工程中完全按經典理論進行套算是不確切的;提出了排樁設計中應定量考慮圈樑的協同作用，側壓力按位移土壓力進行計算的非線形方法。 -
The first, site experiment is carried out. the paper analyze in - situ testing data of subgrade which is made up of plain concrete pile composite foundation and agitation pile composite foundation including pore pressure, layer settlement of soils between piles, earth pressure, lateral deformations
發現正常荷載下，兩種復合地基路基的受力性狀不一樣，用建築垃圾填土樁距較大的素混凝土樁復合地基，淺層應力向樁體集中，並通過樁向深層擴散，樁間土與樁有較大的相對位移，樁頂和樁端的刺入較為明顯。 -
The authors suggest : the internal force ' s value is rational if the coefficient of lateral resistant force is one - forth to one - sixth of tests value, or the coefficient of lateral soil pressure is bigger than the coefficient of earth pressure at rest, or the lateral resistant force is computed together with the lateral earth pressure
提出如將抗力系數取?實驗值1 / 4到1 / 6 ，或土壓力系數稍高於靜止土壓力系數，將側向抗力和側向土壓力綜合?慮，內力計算結果將是合理的。 -
Four types of constitutive models are provided by the code : linear elastic model, duncan - chung model, nonlinear elastic model taking stress path into account and modified three - element model. contact element is used to simulate possible sliding between soil and structure. with this code, analysis is made concerning the pore pressure dissipation, lateral deformation of the support, ground settlement, bottom heave, and variation in earth pressure and support forces ; both effects of consolidation and coupled effects of consolidation and creep are considered ; furthermore, different combinations of cohesion, permeability and excavation width are elaborated
該程序採用了更合理的開挖荷載的計算方法，可以引入線彈性、鄧肯張非線彈性、考慮應力路徑的非線性彈性和修正三元件模型等四種本構模型，並在擋墻和土之間設置薄層接觸面單元以模擬土體和墻體在開挖過程中可能產生的滑移。 -
It brings ollt a fem model to calculate lateral earth pressures behide the integral - abutment with considering the inieraction of eallh and abdrient. aiming at the two inherent behavioral deficiencies inherent in all iabs " summer lateral earth. pressure increases after each temperature cycle ; and the settlement adjacent to each abutment develops after each temperatllre cyc1e, this article brings out two method to solve or relieve the above two problems
本文針對整體式橋臺橋梁的臺后填土存在著土壓力逐年增大以及臺后填土的沉降問題，建立了整體式橋臺橋梁的臺與土共同作用的有限元計算模型；並以臺后填土為研究對象，提出兩種主要處理方法：臺后設置eps壓縮層方案，選用臺後土加筋或置換輕填土方案；通過有限元分析計算了季節性溫度荷載變化下產生的位移在上述處理方法中對于臺後土壓力的影響。 -
The usual methods for earth pressure calculation are summarized. this paper brings forward a displacement earth pressure model. that is the lateral earth pressure on the supporting structure change with the variation of the supporting structure ’ s displacement
本文研究的主要內容如下: 1 、對常用土壓力理論進行綜述后，提出一種位移土壓力模型，即作用於支擋結構前後土壓力的大小隨著支擋結構的變形而變化。 -
