针对探地雷达(GPR)双参数全波形反演中电导率反演精度差、双参数存在串扰现象、反演计算量大、易陷入局部极值等问题.作者将具有多参数调节功能的L-BFGS算法引入到GPR时间域全波形反演中,它避免了对Hessian矩阵的直接存储与精确求解,减小了存储量和计算量.结合参数调节因子的选取,有效减小了同步反演时介电常数与电导率的串扰影响,在不降低介电常数反演精度的前提下,提高电导率参数的反演精度.通过在反演目标函数中加载改进全变差正则化方法,提高了反演的稳定性,使目标体边缘轮廓更加清晰.首先以简单模型为例,对比了单尺度反演与多尺度串行反演策略的优劣,说明多尺度串行反演有利于逐步搜索全局最优解;而开展参数调节因子的选取实验,说明合适的参数调节因子可以有效改善介质电导率的反演精度;测试了不同正则化的反演效果,表明改进全变差正则化能提高反演稳定性,显著降低模型重构误差.最后,分别对含噪合成数据和实测数据进行了反演测试,说明本文提出的多尺度、双参数反演具有较强的鲁棒性,能提供更丰富的信息约束,重构图像界面清晰、反演效果好.

采用地质调查、理论分析、数值模拟与工业性试验等方法,研究了弱面影响下深部倾斜岩层巷道变形特征。该类巷道非均称失稳机制主要包括弱面层间剪切破坏机制、高应力软岩扩容机制与弱面围岩失稳诱发机制。围岩首先沿弱面破坏,弱面层间剪切滑移变形引发邻近围岩破坏区扩展,局部围岩失稳加剧其他部位变形破坏,诱发巷道整体灾变失稳。弱面对巷道失稳起着诱导作用,维护巷道稳定的关键在于控制弱面层间剪切变形与弱面围岩失稳后软岩区域峰后承载阶段的持续变形。基于高强度高预应力控制原则、非均称控制原则与全断面控制原则,开发了以强力支护、弱面围岩加强支护、控制底鼓和二次支护为核心的分阶段动态控制技术,通过强化弱面及围岩整体强度与承载能力,控制巷道非均称变形,保持巷道长期稳定。

Ship energy consumption and emission prediction are the main concern of the shipping industry for ship energy efficiency management and pollution gas emission control. And they are attracting more global attention and research interests because of the increase in global shipping trade volume. As the core of maritime transportation, a large volume of data is collected around ships such as voyage data. Due to the rapid development of computational power and the widely equipped AIS device on ships, the use of maritime big data for improving and monitoring ship’s energy efficiency is becoming possible. In this paper, a fuel consumption and carbon emission model using the artificial neural network (ANN) framework is proposed by using AIS, ship machinery, and weather data. The proposed work is a complete framework including data collection, data cleaning, data clustering and model-building methodology. To obtain the suitable parameters of the model, the number of neurons, data inputs and activate functions were tested on both AIS-based data and MRV-based data for comparison. The results show that the proposed method can provide a solid prediction of ship’s fuel consumption and carbon emissions under varying weather conditions.
