Abstract ：
近年来国内外发生了多起因设计计算过程中忽略了内外坑的影响而造成坑中坑基坑失稳的重大事故，因此坑中坑的整体稳定性分析问题亟待解决。为解决此类问题，文章借助ABAQUS建立三维坑中坑有限元模型，采用强度折减法分析坑中坑基坑内外坑相互影响规律及坑中坑基坑破坏形式，并与传统理论计算方法进行对比。结果表明：主动区塑性区范围及滑裂面位置主要受外围护结构深度影响；坑中坑基坑内外坑间距增加，基坑安全系数不断逼近极限值。

Abstract ：
环境温度变化导致基坑支护结构内支撑轴力和变形过大的问题不容忽视.本文以福州地铁6号线潘墩站坑中坑工程为例,选取该基坑代表性区段采用ABAQUS程序及邓肯-张模型对其开挖和支护全过程进行三维有限元模拟,并将分析结果与现场部分监测数据进行对比,验证了所建模型及其材料参数取值的可靠性.同时,利用所建模型着重分析当地可能的季节或昼夜温差变化幅度内支撑轴力及围护墙水平位移的变化规律.结果表明:基坑开挖完成后,温度变化时支撑轴力与温度呈线性相关关系,轴力变化主要体现在内外坑的首道支撑上,此时围护结构整体向坑内或坑外运动,且地连墙侧移受温度影响范围主要集中在基坑开挖深度以上.不同开挖阶段的温度变化引起的温度效应相差较大,潘墩站最不利工况发生在最后一道支撑架设完毕后,此时地连墙水平位移增量及轴力变化幅度最大,温度效应最明显.该研究成果对类似软土基坑工程具有重要的理论和实践意义.

Abstract ：
The variations of ambient temperature will lead to the increment of axial force and deformation for retaining structures in a foundation pit, which should not be ignored. Taking the pit-in-pit project at Pandun Station of Fuzhou Metro Line 6 as an example, this work simulated the whole process of excavation and construction by the software ABAQUS and Duncan-Chang constitutive model with 3D finite element method. On this basis, the analysis results were compared with the on-site monitor data to verify the reliability of the model and the material parameter values. In addition, the variation regularity of horizontal displacement and axial force of the retaining structure was analyzed with the influence of seasonal or day and night temperature changes. The axial force was linearly related to the temperature after the completion of the foundation pit excavation. The change of the axial force was mainly reflected in the first support of the inner or outer pit and the whole retaining structure moved inside or outside of the pit. The horizontal displacement range of the diaphragm wall affected by the temperatures was mainly concentrated above the excavation depth. The temperature effects caused by temperature changes in different excavation stages were quite different. The most unfavorable condition at Pandun Station occurred after the finish of the last support, the horizontal displacement increment and the change of the axial force were the largest, and the temperature effect was the most obvious. This research will provide important theoretical and practical significance for similar projects. © 2023 Baqiyatallah University of Medical Sciences. All rights reserved.

Abstract ：
[目的]研究坡顶面承重、阻滑双排桩的受力变形特性,分析桩间距、连梁高度、桩身嵌固深度等因素对桩身受力变形特性的一般影响规律,尤其是反映竖向荷载及桩身自由段长度对桩身水平位移及最大弯矩的影响.[方法]借助ABAQUS有限元软件,通过单变量的变化,模拟双排桩在不同影响因素下的受力变形特性.[结果]滑动面的存在使桩身水平位移及弯矩在桩间距为1d～2d(d为桩径)时发生突变,故在确定桩间距时应注意滑动面产生的影响;连梁高度对桩身受力变形特性的影响微乎其微,按标准取值即可;在滑动面位置桩身嵌固深度对桩身水平位移及弯矩有较大影响,但继续增大桩身嵌固深度后,影响变小,在工程设计中桩身嵌固深度适当超过滑动面即可;当增大桩身自由段长度时,P-Δ效应也更加显著,对于不同的自由段长度,前后排桩桩身的最大弯矩近乎相等.[结论]位于坡顶面的双排桩须承受轴、横向复合荷载,可起到承重、阻滑的双重作用,其承载机理及受力形式较护坡桩更为复杂.本文研究成果可为相关工程设计要素的取值提供一定参考.

Abstract ：
To combine the advantages of the Mohr-Coulomb and the Duncan-Chang models, a new model called the nonlinear elastic-perfectly plastic model was established. In the numerical implementation of this model, a newly developed smoothing technique for yield and plastic potential surfaces was employed to accurately fit the side face of the hexagonal pyramid surface of the Mohr-Coulomb criterion. A user material subroutine was developed in Abaqus and was verified by modeling a conventional triaxial test of a soil specimen with the feature of a nonlinear elastic-perfectly plastic model. Finally, to further validate the applicability of this model and its subroutine, the 3D numerical simulation of a relatively complex deep excavation project was performed, and the results were compared with measured data, the results determined by the method recommended in the current code, and the results of the Mohr-Coulomb and Duncan-Chang models. The comparison demonstrates that the results of this new model were the closest to the measurements.

Abstract ：
位于斜坡顶面的复合受荷桩,除受水平及竖向荷载共同作用产生的交叉影响外,还需考虑边坡效应,其承载力特性存在多种影响因素相互交叉作用,复杂程度远高于水平地面受荷桩.本文采用三维有限元软件对坡顶复合受荷桩进行多方面的数值模拟分析,研究发现同级荷载下随复合荷载加载角度增加其极限承载力呈先减小后增大的规律;竖向荷载对桩身水平位移的影响大于其对内力的影响;桩周均布土压力增大将使得桩身位移及内力随之增大;随临坡距增加边坡的影响作用将减小.

Abstract ：
为提高外露段较长的桩在横向和竖向荷载共同作用下变形和内力的计算精度和效率,基于综合刚度原理和双参数法推导可考虑桩的纵横弯曲,即计及竖向荷载(包括桩顶竖向力及桩身自重和桩侧摩阻力)对弯曲变形影响的有限差分解,采用MATLAB程序语言编制相应的计算程序。与模型试验数据或现有方法工程实例计算结果的比较验证了该法的可靠性,同时还表明该方法比基于相同原理的杆系有限元法更方便快捷。研究结果表明:对于外露长度和桩顶竖向荷载较大的桩,重力二阶效应是不容忽视的,且竖向荷载不仅会增大桩身弯矩,还会导致桩身剪力的增大,现有方法未体现其对剪力的影响,是偏于不安全的,在纵横弯曲桩的设计计算中应引起重视。

Abstract ：
为克服现行规范建议采用单参数m法的缺点,将分析水平推力桩的综合刚度原理和双参数法延伸至作用有水平分布荷载的基坑内撑式支护结构变形和内力计算中,建立一种基于此原理和方法的改进的弹性地基梁有限差分算法。此外,为考虑动态施工过程,引入增量法对各工况进行计算分析,并根据现场实测数据,反演出合适的综合刚度和双参数。计算结果表明,该方法得到的水平位移和弯矩,均与实测结果吻合良好,而采用单参数m法却很难使支护结构的位移和内力同时较好地与实测值相符。反分析所得的综合刚度和地基抗力双参数,可应用于同一基坑工程相同结构或同一地区工程地质条件和支护结构相似的设计计算,无疑可获得较现行单参数法更为准确的设计计算结果。

Abstract ：
To improve the accuracy and effectiveness in calculating the deformations and internal forces of piles with large exposure lengths under horizontal and vertical loads, a finite difference solution was established based on the composite stiffness principle and the bi-parameter method. A computation program was compiled by means of MATLAB. The reliability of this approach was verified through comparisons with the measured data from model tests or the calculated results of an engineering example with the existing methods. The comparisons showed that the approach was more convenient and faster than the link finite element method based on the same principle. It was also showed that, for piles with large exposure lengths under vertical loads, the gravity second-order effect must not be ignored and the vertical loads increased not only the bending moments of piles but also the shear forces. The influence of vertical loads on shear forces was not reflected in the current methods, which tended to be unsafe and should be noted in design calculations of vertical and horizontal bending piles. © 2016, Science Press.
