Clast Fabric in Relict Periglacial Colluvium, Salamanca Re-Entrant, Southwestern New York, USA

Samples of macrofabric data obtained from colluvial deposits near the late-Wisconsinan glacial margin display widely divergent characteristics. Those from highly weathered and jointed sandstone plot as girdle distributions. Samples from red colluvium of early-Wisconsinan age form moderately strong clusters. Fabrics from shallow depth in medium-textured brown colluvium of late-Wisconsinan age generally have modes aligned with the local slope but are weak, and appear to have been modified by frost heaving. Clasts in the basal layers of an overlying loess unit were emplaced by frost heaving from the brown colluvium and have very weak or uniform fabrics. Particle shape exerts an influence on fabric strength in the brown colluvium, with samples composed of more elongated clasts displaying stronger fabrics. Fabrics from near-surface deposits show generally weaker shape and strength characteristics and higher inclinations than those at depth. Calculated seasonal frost penetration is consistent with the depth to which weaker, more steeply inclined fabrics are found. Sampling in relict periglacial deposits should be performed only below the level of disturbance by seasonal frost.     

建筑物震害直接经济损失评定的误差分析

本文概述了引起震害损失评定误差的主要因素。通过实际震害评定资料，定量分析了震害损失评估中各因素形成误差数值的大小。采用以采样平均相对误差或采样均方误差及损失值相对误差来评估震害评定质量的方法，并通过分析给出综合衡量评定精度的量化指标，对震害经济损失评定准确度进行评估。

Studies of early comprehensive judgment on seismic tendency after a moderate or strong earthquake

In this paper, the methods of pattern recognition and fuzzy cluster are applied to estimate comprehensive whether there would be an earthquake which magnitude is commensurate with (N=M ₀±0.3) or greatM>M ₀) thanM ₀ within 3 months using sequential data in 3 days immediately after a moderate or strong earthquake (M ₀≥4.7) occurred, The result of retrospective test indicates that the comprehensive judgment effects by using these applied mathematics methods are better than that of using every individual method obviously. TheV mark value of algorithm CORA-3 in pattern recognition is the highest among them. There are 44 known earthquake sequence data (5 type- I and 39 type- II) used to learn and train, the results of internal coincidence test show that all 44 sequence samples could be distinguished correctly. Extrapolation test by using other 4 known earthquake sequences (2 type- I and 2 type- II) shows that all 4 extrapolation samples could be distinguished correctly also. In the process of study, these methods have been applied to judge the post-earthquake tendency of 2 moderate earthquakes occurred recently, one is distinguished correctly and the other wrong. The algorithm Hamming in pattern recognition and fuzzy cluster method have been applied to judge the early post-earthquake tendency after a moderate or strong earthquake, too. TheV mark values of internal coincidence tests could get above 0.8 most cases of extrapolating are correct.
