Optimal earth pressure balance control for shield tunneling based on LS-SVM and PSO

To avoid ground deformation in the process of earth pressure balance (EPB) shield tunneling, it is necessary to keep the earth pressure balance on excavation face. However, at present the earth pressure control depends mainly on operation experiences which is hysteretic and could result in slow response to the change of earth pressure. To solve these problem, a predictive control strategy for earth pressure balance during excavation is proposed in this paper, where an earth pressure prediction model taking advance speed and screw conveyor speed as the control parameters is established by means of least squares support vector machine (LS-SVM). Further, by minimizing the difference between the predicted earth pressure and the desired one, an optimization model of the control parameters is established, and solved by the particle swarm optimization (PSO) algorithm. Therefore, an optimal EPB control scheme for shield tunneling automatically is presented here. The simulation results demonstrate that the method presented in this paper is very effective to control earth pressure balance.

欲穷千里目更上一层楼

文章通过介绍中外合作设计项目“华润大厦”办公楼，阐述了在合作设计过程中几点体会。首先是看到了差距；其次是为了缩短差距，国内建筑师特别是青年建筑师，应该打好基础，从规模了，功能较单一的工程做起，积累经验，并且有选择地积极借鉴国外先进的设计思想和手法；最后呼吁改革现有设计体制中某些不合理的机制和为青年建筑师创作提供较为宽松的环境以及提高他们的社会地位。     

Knowledge-Based Free Mesh Generation of Quadrilateral Elements in Two-Dimensional Domains

Abstract: A knowledge-based system, FREEMESH, for free mesh generation of quadrilateral elements in general two-dimensional structures, is introduced in this paper. Based on the recursive logic, a plane domain is firstly represented with boundary features, corresponding to which a group of heuristic rules is built up to generate quadrilaterals recursively. The niles include the initial design rules and the redesign rules. To facilitate the rule-based inference, the geometric reasoning is turned to acquire domain boundary features. Examples show that this strategy is effective.
