高填石路堤稳定性及沉降规律研究
|
摘要
随着我国西部建设的高速发展，高填石路堤的设计、施工技术及其质量控制方法和评价指标的研究已成为山区高等级公路面临的关键技术之一。本文以广西壮族自治区公路管理局和湖南大学土木工程学院联合承担的科研项目“高路堤施工技术与质量控制研究”为依托，深入研究了高填石路堤稳定性及沉降规律。通过对国内外已有高填石路堤修筑资料的综合分析及室内岩石试验，获得了寨任二级公路高填石路堤地基及填料强度参数的参考值；通过对路堤沉降发展规律现有分析方法的比较及对广西寨任二级公路高填石路堤修筑工程中的沉降全过程观测资料深入分析，运用预测技术，提出了路基及路堤沉降发展规律分析的“龚帕斯”成长曲线分析方法；针对室内岩石试验的局限，运用有限元技术，结合邓肯一张非线性本构模型和复形调优法，提出了高填石路堤填石料强度参数的反演方法，开发了相应的反演分析程序，并成功地反演了广西寨任二级公路高路堤填石料的强度参数值。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。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 rapid development of the constructions in western China, the research on the design and building technology, the quality control and the evaluation parameters of high rock-filled embankment has been one of the key technologies in highway building in mountainous areas. In this paper, thoroughly discussed are stability and settlement laws of high rock-filled embankment based on the joint research project, Research on Construction Technology and Quality Control of High-filled Embankment, by Guangxi Highway Management Bureau and College of Civil Engineering, Hunan University. The reference values of strength parameters of the grounds and rock-fillers of the high rock-filled embankment on Liuzhai-Shuien highway in Guangxi are obtained in this paper by synthetically analyzing the construction technology at home and abroad and indoor rock tests. By comparing the analysis method of settlement laws and thoroughly analyzing the datum of the embankment settlements of Liuzhai-Shuiren highway from the whole cons
truction period, a new method generated from expectation technology to analyze the embankment settlement laws, "Compete" growth curve, is presented in this paper and the result tallies with the observation data. For there are shortcomings in indoor rock tests, in this paper by combining finite element method with Duncan-Chang nonlinear constitutive model and composite method, a method for back analysis of the strength parameters of rock fillers is presented with a corresponding program, which has been successfully applied. 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. 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.
