In this paper, the underground tunnels especially those with prefabricated circu-lar linings of reinforced segments or blocks, by shield construction in the saturatedsilty soft ground of Shanghai area are discussed. On the basis of field measurementsand laboratory tests, the Chain Theory that the distribution of soil pressure aroundthe tunnel is approximately uniform, the elastic theoryof circular ring under loosening soil pressure, and the design method considering the stiffness of the ring jointsare proposed,...

In this paper, the underground tunnels especially those with prefabricated circu-lar linings of reinforced segments or blocks, by shield construction in the saturatedsilty soft ground of Shanghai area are discussed. On the basis of field measurementsand laboratory tests, the Chain Theory that the distribution of soil pressure aroundthe tunnel is approximately uniform, the elastic theoryof circular ring under loosening soil pressure, and the design method considering the stiffness of the ring jointsare proposed, the design models and parameters of the stratum and structures aresuggested. This mehtod has better confomity with the site realities than the conventionalway. lt yields thinner lining sections, less reinforcements and simpler jointwork, thus helping lead to the advantage of engineering cost and construction speed.

本文介绍了上海地区含水饱和淤泥质软土地层中地下工程的设计理论,主要为盾构法施工的装配式圆形钢筋混凝土管片和砌块衬砌结构。在现场量测和室内相似试验的基础上,提出了周围土压接近均匀的链条理论、松动压力下弹性圆环理论和考虑接头刚度的设计方法,并建议了设计时采用的地层和结构的模型及参数。采用本文方法,比习用设计方法更符合客观实际,可以使衬砌减薄、钢筋用量减少,接头构造简单,达到进一步节省投资和加快建设的效果。

Based on many years research of broken rock zone the paper describes roadway support theory, classification of rocks in the loose rock zone and mechanism of rock-bolting and shotcreting. Field and lab tests show that interaction between rocks and earth pressure produce different size of broken rock zone; that the bulking force resulted from expansion of the broken zone and thus caused deformation is the major objective of roadway support; and that the larger the extent of broken rock zone, the greater the roadway...

Based on many years research of broken rock zone the paper describes roadway support theory, classification of rocks in the loose rock zone and mechanism of rock-bolting and shotcreting. Field and lab tests show that interaction between rocks and earth pressure produce different size of broken rock zone; that the bulking force resulted from expansion of the broken zone and thus caused deformation is the major objective of roadway support; and that the larger the extent of broken rock zone, the greater the roadway convergence, and it is more difficult to support.However, the effect of broken zone on the support is not obvious in site, a and therefore the size of broken rock zone is used as an index for classification of the surrounding rock, and it is scientific and rational. This was proved to be correct by field practice. The mechanism of rock-bolting and shotcreting changes with the size of broken rock zone,therefore,the design of support should be changed accordingly. It is suggested to investigate further the bulking force of rock-breaking, that is, attention should be attached to post-failure nature of rocks.

基于多年对围岩松动圈的研究成果,本文提出并论述了松动圈支护理论、松动圈围岩分类方法和锚喷支护机理三个问题。现场实践和实验室研究表明:地应力与围岩的相互作用会产生大小不同的围岩松动圈;松动圈扩展过程中产生的碎胀力及其所造成的有害变形是巷道支护的主要对象;松动圈尺寸越大,巷道收敛变形也越大,支护越困难。而在现场条件下,支护对松动圈的影响并不明显,因此,取松动圈尺寸作为围岩分类指标是科学的、合理的,已经大量实践所证实。松动圈尺寸不同,锚喷的作用机理也不同,因而应采用不同的设计方法。本文建议加强岩石碎胀力的研究,即重视岩石破坏后性质的研究工作。
