土质边坡分析中的极限平衡法与有限元强度折减法的研究

介绍边坡分析的极限平衡法与有限元强度折减法原理,比较两者优缺点。对均质土坡分别采用有限元强度折减法与极限平衡法进行计算,得到相应的安全系数和潜在破坏面,得到两种方法所得安全系数和破坏面一致的结论,应用有限元强度折减法计算是合理可行的。

Central bank disclosure as a macroprudential tool for financial stability

The Basel Capital Accord (pillar 3) states that disclosure of information (transparency) is essential to financial stability. This study analyzes, through inflation reports, the disclosure of information from the Central Bank of Brazil concerning the credit market. We consider credit risk and capital buffers as measures of financial stability in this analysis. Furthermore, in order to measure the perception of the monetary authority on the credit market, we built two indices based on the central bank’s communication on credit development. We performed a panel data analysis based on a sample of 125 banks for the period from June 1999 to September 2014 (7000 observations). The findings suggest that central bank communication regarding expectations concerning the credit market contributes to financial stability. Therefore, this kind of communication of central banks (about credit development) may constitute an important macroprudential tool to improve financial stability.     

Quantitative Easing Forever? Financialisation and the Institutional Legitimacy of the Federal Reserve’s Unconventional Monetary Policy

Scholars of financialisation have argued that the emergence of finance-led grow regimes requires new instruments for effective conduct of economic policy. In this scholarship, central banks have been seen as the most promising actors to utilise one of the most synergetic policies, the maintenance of high and stable prices of financial assets. Since the financial crisis of 2007–8, central banks of the developed world have adopted various unconventional monetary policy measures that serve this function. But will these unconventional measures become institutionally legitimate and institutionalised as conventional practice, as suggested necessary by scholars of financialisation? In this paper, we answer to this question by studying the institutional legitimation of the Federal Reserve’s Quantiative Easing (QE) programmes. We argue that the QE programmes have been legitimated successfully but with institutional legitimation strategies, which cause institutional pressures that question the potential of QE from becoming a regular policy instrument and practice.

Bank competition,concentration and financial stability in the Turkish banking industry

This paper analyzes the impact of competition and concentration on bank stability in the Turkish banking industry over the period 2002–2012. The Boone indicator and the efficiency-adjusted Lerner index are used as proxies for competition, while the non-performing loans (NPL) ratio and Z-scores are used as proxies for bank stability. The main results indicate that competition is negatively related to the NPL ratio but positively related to the Z-score. The results further indicate that greater concentration has a positive impact on the NPL and a negative impact on the Z-score. We also use a quadratic term of the competition measures to capture a possible non-linear relationship between competition and stability. The results show that the coefficient of the quadratic term is negative for the NPL model and positive for the Z-score model. Overall, our findings provide support for the competition-fragility view.     

多级斜坡路基软弱地基变形机理和稳定性数值分析

山区公路路基往往是在斜坡上填筑的,这种填筑形式更易于发生变形破坏,故本文以某斜坡路基为研究对象,研究斜坡路基地基变形机理,并用强度折减法分析该斜坡路基的稳定性。结果表明:①地基形变的总体趋势以沉降变形为主,随填筑高度的增加,水平位移逐渐趋于均匀,并表现为侧向外鼓,沉降最大值集中在与填筑体中心相交的区域。②路基中心的最终沉降位移相较于坡脚的2倍;路基整体有向斜坡下滑移的趋势;短坡脚的水平位移发展最快。③斜坡路基随填筑高度的增加,从深层滑动发展为浅层滑动,滑体集中于长坡脚。④随填筑高度的增加,安全系数逐渐降低。
