山地人居环境设计的缘地策略研究

缘地策略既是一种技术策略,又是一种文化策略。针对山地人居环境建设的复杂性,指出山地人居环境设计应从狭义的缘地策略走向广义的缘地策略,并对相应的生态整体规划、生物气候设计、适宜性生态技术设计等策略进行探讨,旨在强调通过形态、生态、文态的深度整合,实现山地人居环境的整体适应性,体现缘地性的生态内涵、美学价值、地域文化和意义。

Correction to Shirom.

Reports an error in the original article by Shirom (Journal of Applied Psychology. Vol 67(1) Feb 1982, 45-52). a percentage was incorrectly reported. On page 45, the fourth line from the bottom of the abstract, the value 21% should read 12%. In addition, one of the values in Table 2 (page 50) was incorrectly labeled significant. The asterisk for the value .21 (the adjusted mean for R2) should be deleted. (The following abstract of this article originally appeared in record 1982-10870-001.) Management perceptions of advantageous settlements of strikes were predicted by the extent to which the struck plant was kept in operation, the extent to which a mediator was involved, frequency of strikes in the plant in the past, duration of the strike and its breadth. Data from 51 chief management negotiators show that past frequency, duration, and a mediator's involvement were not significant as predictors. The management's perception of strike settlement as advantageous was found to be positively affected either by large breadth of the strike or by the management's success in keeping the plant in operation during the strike. Results indicate that management's power to resist strikes by operating the struck plant is a significant predictor. Findings cast doubt on the notion that unions are successful in identifying as strike targets employers who are vulnerable to the costs imposed by a strike.

Design and construction of lightweight EPS geofoam embedded geomaterial embankment system for control of settlements

This paper presents a research study on a bridge site located along US highway 67 over SH 174 in Cleburne, Texas, where bridge approach slabs have experienced more than 0.4 m (17 in.) of settlement within a span of 16 years after construction. Many treatment methods attempted to mitigate this problem had proven to be ineffective. As part of novel rehabilitation works, the top of existing fill soil on the embankment was replaced with lightweight expanded polystyrene (EPS) geofoam blocks to alleviate the approach slab settlements. This paper describes initial design and construction details of the rehabilitation works performed on the embankment system along with a focus on the early performance details. Field monitoring studies were conducted for almost three years to study the bump/settlements under the EPS geofoam embankment system. Short term measured settlement data was analyzed with hyperbolic model to predict the long term settlements. Numerical finite element studies attempted in this study showed that settlements could be reasonably predicted by modeling these geofoam embankments. Based on the monitoring and modeling studies, the effectiveness of utilizing EPS geofoam as an embankment fill material was addressed to mitigate the differential settlements under a bridge approach slab.     

Seismic stability of embankments with different densities and upstream conditions related to the water level

Modeling an embankment by subjecting it to different upstream conditions in a centrifuge is challenging. However, the response of an embankment to shaking under different upstream conditions needs to be studied to ensure that the necessary precautions are taken during its construction and maintenance. Herein, the influence of different upstream conditions and embankment densities are investigated. The pore water pressure values at different locations in an embankment were recorded during seepage and under induced shaking. Accelerometers recorded the response of the embankment to shaking, and a linear variable differential transformer (LVDT) measured the settlement at the top of the embankment as a result of the shaking. An image analysis was used to trace the resulting deformation of the embankment due to the shaking. The results indicate that the upstream conditions of the embankment determine the failure mechanism of the embankment in cases of lower density. In addition, the distribution of the water content within the embankment was found to have a greater influence on its response to shaking than the water level height on its upstream side.     

尾矿库堆积坝排渗设施在某尾矿库的应用

近些年受尾矿库选址及环境保护等政策的限制，新建尾矿库的工程投资明显增加，因此在原有堆坝高度上继续加高的工程增多，接近100～200 m级的高坝尾矿库大量涌现。为增加尾矿库的稳定性，以某尾矿库工程为例，坝体浸润线埋深较高，稳定计算不能满足相关规范要求。为有效降低浸润线，在堆积坝内采用大口辐射井和飘管相结合的排渗设施。经现场实际运行，排渗设施的应用对保证坝体稳定具有十分重要的作用。
