人工填土中灌注桩水平静载试验研究

桩基础的水平承载力受多种因素影响,很难精确计算。《建筑桩基技术规范》(JGJ94-2008)规定:对于受水平荷载较大的设计等级为甲级、乙级的建筑桩基,单桩水平承载力特征值应通过单桩水平静载试验确定。某工程开展结构设计前,对人工填土中的灌注桩进行了低应变桩身完整性测试和水平静载试验,并量测了试验过程中基桩的内力、位移等参数。通过对试验数据的整理、分析得出以下结论:由于人工填土不均匀,试验的水平抗力系数的比例系数离散性较大,属于复杂的地基环境,应做水平静载试验才能获取可靠的水平承载力值;成桩质量对灌注桩水平承载力影响较大,应对水平荷载较大的桩进行桩身完整性试验,确定成桩质量;桩周土水平承载主要影响深度试验值与理论值基本一致。

求解网络编码优化问题的混合启发式算法

网络编码是一种在新时代下提出的网络传播技术,不同于传统网络传输技术,网络编码所赋能的编码传输能力使它能有效提高网络吞吐量,提升传输效率。但与此同时,也带来了编解码的开销。因此,为保证网络编码带来效能的同时,降低网络编码的额外开销,论文首先建立了在代数网络编码框架下的系统优化模型,并以该模型为基础,提出了一种求解网络编码优化问题的混合启发式算法。该算法在改进传统遗传算法的基础上引入了禁忌搜索算法,提高了算法的收敛速度。实验结果表明,该算法可以有效降低网络编码开销,同时与传统的遗传算法相比,具有更好的收敛性。

The Cultural Impact of Chinese Students' Self-Construals on Communication Competence

The purpose of the study sets out to address issues, such as whether the mainland Chinese students better develop interdependent self-construals than the Chinese sojourners, and to what extent a Western cultural context affects the Chinese sojourners’ perceptions of self-construals on interdependence and independence. This research compares a sample of 40 mainland Chinese students and a sample of 20 Chinese sojourners studying in Wales. The respondents were asked to complete a structured self-completion questionnaire. The findings seem to suggest that culture teaches one how to think, conditions one how to feel, and instructs one how to act, especially how to interact with others. It concludes that both the mainland Chinese students and the Chinese sojourners have well-developed interdependent self-construals and independent self-construals. It is also suggested that the traditional cultural values brought with the Chinese sojourners have been well-preserved in a Western cultural context.
