摘要:
基于双剪统一强度理论,将作用在挡土墙上的土压力视为空间问题,推导出空间主动土压力双剪统一解的简化计算公式,讨论了中间主剪应力影响系数对主动土压力及其参数的影响,并与已有文献的实例进行对比分析。计算结果表明:推导出的土压力及土压力系数公式可适用于各种不同特性材料的空间土压力简化计算; 得出的解具有广泛代表性; 随着中间主剪应力影响系数的增大,空间主动土压力减小,土压力系数及土压力作用点距墙顶的竖直距离均略有减小; 通过变换中间主剪应力影响系数值可获得一系列的解; 在工程运用中可根据土质和工程的实际情况,适当选择统一强度参数来确定土压力的大小。
Abstract:
Based on twin-shear unified strength theory, the simplified calculation formula of twin-shear unified solution of space active earth pressure was derived when the earth pressure acted on retaining wall was taken as the spatial problem. The intermediate principal shear stress influence coefficient was discussed and the effect on active earth pressure and its parameters were investigated.The comparison with the existing reference was taken. The calculation results show that the earth pressure and its coefficient formula can be suitable for all kinds of different material behaviors; the space active earth pressure decreases with increasing of the intermediate principal stress influence coefficient; the coefficient of earth pressure and the vertical distance from the position of earth pressure to the top of retaining wall decrease slightly; good agreement can be observed from the comparison between the results of reference and that of this paper; a series of solutions can be obtained through transforming intermediate principal stress influence coefficient; the earth pressure can be determined by choosing suitable unified strength parameters in terms of earth behavior and practice situation in engineering application.
