无底圆筒结构内填土压力分布和抗倾有效比计算

由于无底圆筒结构与有底结构相比,在结构沉降、基底应力等方面存在差异,导致二者的内填土压力分布明显不同,因此,传统的贮仓压力理论不能正确确定无底圆筒结构的筒内填土压力．采用模型试验,量测作用在无底圆筒结构上的土压力,分析无底圆筒结构与内填土和地基的相互作用,探讨圆筒结构在倾覆过程中内填土与筒壁间摩阻力调整机理．通过试验研究和理论分析得到,在对称荷栽作用下筒内土压力分布分为三个区域,在非对称荷栽作用下,由于筒内产生附加力矩而使土压力分布变为两个区域,且抗倾有效比约为对称荷栽状况下的1．10倍,在此基础上,提出了对称荷栽和非对称荷栽(作用有侧向荷载)情况下,筒内填土压力和抗倾有效比的计算方法,前者适用于圆筒施工期的计算,后者适用于使用期的计算．     

A Maturing of Systems Thinking? Evidence from Three Perspectives

This paper reviews trends in systems theory/thinking from the 1970s to the early 2000s. It proposes a maturation of the field based on certain conceptual and methodological advances that have sought to liberate systems thinking from earlier strictures. An edited dialogue among three prominent systems thinkers from different systems schools—Merrelyn Emery, Bob Flood, and Eric Wolstenholme—provides evidence. Similarities and differences are identified, complementarities among the schools are derived and analyzed, and trajectories for future research are indicated.     

The generalized inverse of singular integral operators on an open arc and its applications

After choosing weight functions suitably, we define a Banach spaceH _ω ^μ (L) and discuss the generalized inverse of singular integral operators on an open arc. Using the generalized inverse, we obtain the solutions for the following singular integral equation

The Third Track of the Open-Systems-Thinking School: An Application of Domain Theory to New Zealand Ports

The Open-Systems Thinking (OST) school identified with Emery and Trist is situated as an important but underutilized approach in systems thinking. The main features of OST are described, including four "tracks" along which OST has developed. The third track, which focuses on interorganizational domains, is considered in detail. It is then applied to a case concerning the complex social dynamics of and in port domains in New Zealand. This exercise enables us to illuminate some lacunae in previous representations of the port domain research, to assess OST's third track regarding its relevance for systemic practice, and to help to bring OST to the table with other systems approaches that are all vying for the attention of researchers, practicing managers, students, and consultants.
