The elastic stress diagram design method is behind the times and cant meet the command in practice.In the paper the author collected and analyzed a large amount of data about the SLRCP on several typical domestic model experiments and the projects in practice. By summarizing and analyzing the data, the author set up a typical computing model and analyzed the model by the software ANSYS, by reading the output data of the stress and the crack from the program, combined with the experimental results, the author summarized the destroy procession of the stock. The paper also discussed the influence of other main factors to the crack and the stress besides the internal water pressure, such as the concrete material, the dimension of stock and the way of laid-out steel bars.

本文通过对大量实际工程中的坝后背管资料的收集、归纳和分析，选取了具有代表性的计算模型；用有限元软件ANSYS计算了典型坝后背管结构在实际内水压力作用下的应力分布和裂缝发展情况；以国内几个有代表性的模型试验和有限元计算的成果为依据，分析了在内水压力作用下钢衬钢筋混凝土压力管道管壁裂缝的特点，并尝试总结出此种管道的裂缝出现的原因及其发展规律，同时确定了坝后背管结构极限状态的新的定义方式——以坝后背管的裂缝宽度来定义。

Based on the findings and some advanced experience from developed countries, this paper gives out some policy advice. For instance, the central government should set the elementary education fiscal investment as a fixed proportion to local GDP; the provinces with population outflow should get some inter-governmental grants to encourage the development of local elementary education. In the trend of fiscal decentralization, this paper is trying to figure out a trade off between the efficiency and the fairness of elementary education.

在此基础上，本文通过借鉴发达国家对于基础教育财政投入的经验，提出了设定基础教育财政占地方GDP的比例，根据人口流动特征对人口流出省进行基础教育经费补贴等政策性建议，以期能够探索性地提出一些政策思路，力图在教育财政分权的过程中，在基础教育的办学效率和公平之间找到一种更为有效的平衡。
