| 1. | Experimental investigation on movement of deep soil mass caused by pipe jacking 顶管施工引起深层土体移动的试验研究 |
| 2. | In addition , the influence factors of sub - surface movements are also analyzed 另外还探讨了深层土体移动的影响因素。 |
| 3. | On the nitrate - n accumulated characteristics in deep soil layer of winter wheat field in taihang piedmont 太行山山前平原冬小麦田深层土体硝态氮累积特征研究 |
| 4. | This paper introduces the concrete methods of deep cement soil stir as compound foundation and suggests should pay attention to some questions of designing and construction 摘要通过实例介绍深层土搅拌桩作为复合地基的具体做法,并提出了设计与施工中应注意的问题。 |
| 5. | The tendency of deformation of deep stratum was consistent with that of the shallow stratum , but the settlement of deep stratum over the tunnel was far larger than that of the shallow stratum 隧道开挖引起的地层深层与浅层变形趋势是一致的,但在两隧道轴线上方深层土体的沉降要远比浅层土体大。 |
| 6. | Calculation results show that the suction of the soil close to slope surface is mainly controlled by rainfall infiltration and evaporation , while the deeper soil ' s suction is controlled by the gravity and groundwater conditions 指出非饱和土边坡近坡面土体吸力主要受入渗、蒸发条件控制,而深层土体吸力主要受重力及地下水条件控制。 |
| 7. | The test study change of the soil pressure , the touch pressure between pipe and soil , pore pressure , the movement of depth soil , the underwater level and the deformation of earth surface in process of pipe jacking 研究了顶管施工过程中引起的土压力、土体与管壁的接触压力、孔隙水压力、深层土体位移、地下水位的变化以及地表变形等的影响。 |
| 8. | Fourthly , the author has discribed environment monitoring technology relating to the effect of pile driving , and has proposed some operating index . at last , the problem of pile group is qualitatively analysed , some conclusions about soil displacement are obtained 最后,联系工程实例对群桩施工中深层土体位移问题作了定性分析,总结出桩周土体位移变化的一般规律。 |
| 9. | The expressions can take into account some important aspects such as stress - free ground surface , incompression of soil , prebored hole and tubular pile . through the analysis of displacement field , the variation rules of horizontal and vertical displacements are obtained 由位移场的解析解分析可知,桩身整个深度内的水平向位移场是向外挤出,竖向位移场在表层土体表现为隆起,而深层土体表现为下沉。 |
| 10. | By analysis the results of in - situ monitoring in the process of pipe jacking , the law of surface deformation perpendicular to pipe axis and along pipe axis , the sub - surface movements perpendicular to the axis of pipe and along the axis of pipe are studied 通过对顶管工程现场测试数据的分析,研究了顶管施工引起的管道周围土体的移动规律,包括地面横截面和纵向截面变形规律、深层土体沿管道轴线方向和垂直于管壁方向移动规律。 |
