- Abstract : based on engineering practices , this paper introduces the design , construction technique and monitoring conditions of the artificial dig - hole pile water - interception curtain in strongly permeable layer under complex environmental circumstances
文摘:该文根据工程实践，介绍了复杂环境条件下，强透水地层中，人工挖孔桩截水帷幕的设计、施工技术及监测情况。 - Thus , the piping - induced failure of two - layer foundation was verified as that ： mass flow firstly appears in the upper weakly permeable layer , and then underground erosion and scouring gradually occur from downstream to upstream between the serviously and weakly permeable layers
从而验证了二元结构堤基的渗透破坏模式为：首先在上层弱透水层中发生流土，然后在强、弱透水层之间发生自下游向上游的逐步潜蚀冲刷。 - It is commonly recognized that subsurface drainage system can improve pavement performance and extend service life . as an essential part of subsurface drainage system , the layer setting and characteristics of asphalt treated permeable material directly affect the performance of subsurface drainage system , which is lucubrated in this paper . based on the typical semi - rigid pavement without permeable layer , using multilayer elastic system program , rational pavement structure with permeable layer at different locations is first analyzed
本文以高等级公路沥青路面的典型结构形式作为未设排水层的路面结构原型，通过不同的设置层位分析对排水层的回弹模量和厚度的要求，探讨设置排水层的路面结构的一些结构参数适宜的取值范围，并在此基础上运用灰色系统关联分析方法，对不同设置层位的路面结构的技术指标进行比较分析，得出较优的层位设置方案。 - By structural analysis and calculation for original highway structure without permeable layer , the critical modulus of base have been obtained which makes asphalt pavement fill different allowable stress criterion . by structural analysis and calculation for different highway structure with permeable layer , critical modulus of permeable base course are obtained to make asphalt pavement fill different allowable stress criterion . the paper also presents the tendency of structure response of different highway structure with drainable layers mainly depends on the thickness of asphalt pavement , the thickness and the critical modulus of permeable base
对于不设排水层的原路面结构，通过结构计算得出对应于不同的沥青面层容许应力值时所需的基层临界模量值；对于加设排水层的路面结构，通过结构计算得出对应于不同的沥青面层容许应力值时所需的排水基层临界模量值；加设排水层的路面结构的结构反应的变化趋势主要取决于沥青面层厚度、排水基层厚度和排水基层临界模量值。 - 3 . the carstic formation is permeable layer and has quite good placeability , its relations of the water permeabitity and placeability have three types as follows : high unit - absorption rate with big grout consumption , the grouting is necessary ; low unit - absorption rate with little grout consumption , the grouting is no need ; low unit - absorption rate with big grout consumption , grouting is no need combining with control the grouting pressure and grout consumption . 4
岩体透水率与可灌性之间一般存在以下三种组合关系：高单位吸水率与大吃浆量的组合，灌浆是必需的；低单位吸水率与小吃浆量的组合，没有必要灌浆；低单位吸水率与大吃浆量的组合，应进行灌浆处理，但应适当控制灌浆压力和耗浆量。
