【摘要】 在土钉支护边坡的工程中,土钉布置参数对边坡的支护效果有着重要的影响。通过 Plaxis 有限元程序,分析了土钉长度、土钉植入边坡的高度以及土钉间距对边坡安全系数的影响。通过分析,结果表明,当土钉长度增加或土钉间距减小时,边坡安全系数增大;土钉植入边坡底部比土钉植入边坡中部或上部更能提高边坡安全系数。并且在分析的基础上,提出了一种综合考虑土钉布置参数的土钉布置方式,以期对土钉布置设计提供建议和参考,以取得较好的经济性和安全性。更多还原

【Abstract】 In soil nails enforce slope projects,the disposal parameters of the soil nails influence the slope stability obviously.Plaxis finite elements method procedure was adopted to analyze the length of soil nails,height of soil nails embedded into the slope and the spacing of soil nails effect on the slope stability. The results showed that when the soil nails length increase or the spacing of soil nails decrease,slope safety factor increases;Soil nails embedded into the bottom of the slope than soil nails embedded into the central or upper of the slope can increase the safety factor of the slope dramatically.And on the basis of the analysis, a disposal method were proposed with consideration comprehensive the disposal parameters of soil nails,ex- cept could providing advices and references for soil nails design,and achieve better economics and security更多还原
