Mechanical properties of aging dams and rock foundations can differ significantly from those design values used during construction.It is necessary to conduct the inverse analysis of mechanical parame
高速铁路对路基、桥涵、隧道等线下工程的工后沉降要求十分严格,而现有的沉降设计计算受到多种因素的影响,计算精度不足以控制无砟轨道工后沉降.因此,工后沉降的控制应以施工期间系统的沉降观测与综合分析评估为主.通过对沉降观测数据系统的综合分析评估、验证或调整设计措施,使路基,桥涵、隧道工程达到规定的变形控制要求,分析推算出最终沉降量和工后沉降,对合理的确定无砟轨道开始铺设时间,确保高速铁路无砟轨道结构铺设
垂线监测作为大坝变形监测的主要手段,一直是大坝安全资料分析、评价的关键项目.本文简要介绍了山口岩大坝垂线监测布置情况,分析了近4年的垂线实测资料,初步讨论坝体水平位移变化的规律.通过监测成果分析表明,大坝垂线系统布置合理,监测仪器工作性态正常,监测数据所反映的大坝位移变化趋势与水位相关性较好,垂线监测系统为大坝安全稳定运行提供了良好的保障.
An inverse modeling process is proposed to estimate the actual elasticity modulus of a high arch dam based on unconstrained Lagrange support vector regression (ULSVR) and monitoring data.The proposed
Many designed and measured values in anti-sliding stability of gravity dam are uncertain.Most of existing fuzzy-random risk analysis methods are based on the possibility theory and describe structural
Timely diagnosis of the service condition of concrete dam is required to prevent the potential great loss of life and property in case of dam failure.Scientific and reliable diagnosis indexes are sign
For dams and rock foundations of ages, the actual mechanical parameters are sometimes differed from the design and the experimental values.Therefore, it is necessary to carry out the inversion analysi
南水北调中线为长距离线性输水工程,沿途布置大量输排水和交叉跨越建筑物.线性工程特点,决定了基准点难以远离变形区域,膨胀土遇水易形成浅表水土流失和深部滑移,对基准点选点和稳定构成严重挑战.文中对垂直位移监测基准层次、基点稳定、观测及数据处理、基点稳定检测等关键技术进行了研究,确立了膨胀土区垂直位移监测基准建立的一整套方案.基准网建立后,经过中线通水试验、全线试通水以及运行初期长达2年多的检验,证明上
