Abstract: A high slope with a length over 400 meters will be formed at the Lianyungang nuclear power station after the second period of engineering excavation. After systematically analyzing the engineering geological conditions, the stability of the slope is evaluated by means of engineering comparison and pole projection in corporation with limiting equilibrium method and two-dimensional and three-dimensional finite element method, and the slope design plan is also made.

Abstract: An anisotropic damage tensor is developed to consider the geometrical and mechanical effects of intermittent joints in rockmass. By means of numerical analysis, the influence of different geometrical distributions of joint sets is considered on the deformation and stability of the high steep rock slope during slope excavation. The results are useful for the design and deformation monitoring in excavation of rock slope.

Abstract: Based on unloading characteristics of rockmasses during excavation,this paper presents a criterion for loaded and unloaded mechanisms,and establishes a brittle elastoplasticity model of rocks. The model and criterion are then applied to a stability analysis of excavated high slope of the Xiaowan hydropower station project. The combination of the model and criterion with a three-dimensional nonlinear finite element method provides a technique for the selection and optimization of reinforcement measures.

Abstract: In light of the fact that the decision making of treatment schemes of slopes is a comprehensive multi-objective and multi-hierarchical judgment problem, and a fuzzy property of its evaluation indexes is involved, a fuzzy hierarchy analysis on decision making of rockmass slope treatment based on entropy weight is presented in this paper. According to the two-two index comparison, the triangle fuzzy numbers are adopted to establish judgment matrix. Thus the unbalance of judgment matrix caused by traditional hierarchy analysis is improved. The entropy weight is given through fuzzy interval arithmetic based on level sets and optimistic index. Then the treatment schemes of rockmass slope are evaluated on the basis of entropy weight. The assessment of treatment schemes of critical rockmass on the Slate Mountain is taken as an example, and the application of the method is discussed in detail. The result shows that fuzzy analysis hierarchy process of decision making for rockmass slope treatment based on entropy weight is scientific and reasonable, and has important value for engineering application.

Abstract: 摘要 多级框架锚杆是加固高边坡的一种常用工程结构,合理确定其在边坡分级开挖过程中所承受的坡体压力荷载是设计计算的关键环节之一。依托遂资高速公路一路堑高边坡多级框架锚杆加固工程,采用室内模型试验方法,模拟了边坡分级开挖施工过程,获得了各级锚杆框架梁上的坡体压力分布规律和变化特征,以及下面坡级开挖对上面坡级的锚杆框架梁上坡体压力的影响特征。结果表明,各级坡框架梁上坡体压力整体均具有中间大两端小的特点,在下面的1—2级坡体开挖完成后的工况是各级框架梁受力的最不利工况,在工程设计中应主要以这些工况作为各级框架梁的控制设计的工况。

Abstract: According to the field measurements, the characteristics and the mechanism of the rockmass deformation of temporary shiplock and boatlift slope are analysed. It is considered that the formation and mechanism of rockmass deformation are closly connected with the discontinuity type and its distribution in the slope. Even for the slope of hard granite, creep deformation is exactly existed, and it is also very important to the slope stability.

Abstract: In the construction of civil engineering,the local environment will be destroyed.Not only is the greening project advantageous to resume the natural environment destroyed,but also the roots of vegetation will strengthen the surface of slope.In respect of vegetation growing,the slope is reclassified;the roots protection mechanism is studied.Then the stability of the protecting layer is studied by test and numerical simulation.The results show that the effect is different for different structures of rock mass.In order to guarantee the stability of the protecting layer of slope,according to the classification,height and slope rate,the proper methods with other measures should be applied.
