This paper conbined with the indoor test and the scene test road , through the synthetical analysis of the factors of influencing densification effect for the densification thickness of filling stone roadbed . the maximum grain size of fill material , densification machinery and densification frequency et al . advanced a control norm of the maximum grain size and piy of compression , established ration evaluating the control standard of densification quality of filling stone roadbed under overload . comparing with result of indoor test and the scene test road , studied on theory of densification in different kinds of stone material and perfected the control system of the densification of filling stone roadbed under overload 结合室内试验和现场试验路的实测数据,通过对填石路基的压实厚度,填料最大粒径,压实机械及压实遍数等影响压实效果的因素的综合分析,提出填石路基的最大粒径和摊铺厚度的控制指标,建立定量评定超重载交通下填石路基压实质量的控制标准,并对照室内试验和现场试验结果,研究不同石料条件下的压实理论,补充完善了填石路基压实控制指标体系。
By thoroughly analyzing the methods on slope stability of high rock - filled embankment , in this paper , a new kind of composite evolutionary algorithm is formed to search the critical slippage surface and also discussed in this paper is a new way to simplify the procedure of general slice method for stability analysis 本文还通过对目前国内外高路堤边坡稳定性分析方法的综合分析和深入探讨,简化了极限平衡法中的通用条分法的求解过程,并结合现代优化方法,提出一种新型的混合演化算法对高填石路堤边坡临界滑动面进行搜索。
During the research period , by combining theory analysis with engineering practice , the field tests in three sections with high rock - filled embankments , which are over 30m hig h , are put over . through the tests , plenty of valuable field data are obtained which will be helpful in the highway constructions in western china in the future 此外,本文结合理论分析与工程实践,成功地完成了三段高达30余米的高填石路堤的现场试验路,通过周密系统的分层沉降观测和分类现场检测,取得了丰富的现场资料,为今后西部高等级公路建设积累了宝贵的经验和数据。
With the retrospection of the developing course of the bored pile foundation and combining with my practical experience , the paper expatiates upon the design principle of percent of fit of the stone - fill grouted concrete and the main factors of the influence strength target , and the final pile technique introduction of the hollow pile of the stone - fill grouted concrete and the precast prestressed concrete ; baesd on the theory of slurry hydraulics , empirical calculation formulas of the radis and height of diffuse slurry are deduced in this paper ; it analyzes the test pile materials of the hollow pile foundation , such as luoyang yi river bridge and dangwang jian river bridge ; the new technique of the hollow pile , which provides the generalization and application with base materials , expounds its feasibilities , adaptabilities and economy 本文通过综合分析国内外钻孔桩基础的发展历程及研究现状,重点讨论了填石压浆混凝土空心桩、预制预应力混凝土空心桩的成桩工艺、填石压浆混凝土的配合比设计原理及影响强度指标的主要因素;根据泥浆水力学原理,导得了考虑各种因素的水泥浆液在预填骨料中的流动影响半径和上升高度;结合河南省洛阳伊河大桥、党湾涧河大桥工程实践,讨论了填石压浆混凝土空心桩基础的质量检测方法及标准;并在此基础上,深入分析了桩侧、桩端承载能力,提出了填石压浆混凝土空心桩的设计计算理论和方法。最后,论证了空心桩新工艺的可行性、适应性、经济性,为大力推广应用空心桩新技术提供了可靠的技术资料。
