Considering the possibility to improve the properties of the lime - loess , certain experiments about the strength and water - stability of cement - lime - loess was done . some properties of the cement - lime - loess was developed and used in practice 考虑灰土改性的可能性,作者还做了一定数量水泥灰土的强度试验和水稳定性试验,得出水泥灰土的一些工程性质,并将之应用于工程实践。
About mixture rate of calcium carbide dust stabilization and calcium carbide dust s mixing dose , controlling methodand construct technics , we conduct large number of indoor tests and outdoor tests and educe scientific datas and methods 对于电石灰稳定土、电石灰二灰土和电石灰二灰稳定级配碎石的配合比以及电石灰的掺和剂量、控制方法、施工操作工艺等都做了大量的室内、室外试验,得出比较科学的数据和方法。
I think that what we actually need , of course , is a little more dirt on the seat of our pants as we sit on the front stoop and talk to our neighbors once again , enjoying the type of summer day where the smell of garlic travels slightly faster than the speed of sound 我认为我们真正需要的应该是裤子后档多沾上一点灰土,坐在门户阶上再次与邻居谈天说地,享受着夏日的闲暇,那时大蒜的气味比音速传得还略快些。
Through a large number of unconfined compression tests and triaxial compression tests , the strength property and the water - stability of the lime - loess was analyzed . some laws about the strength property of the lime - loess with different lime content and compaction work varying with time were developed 本文通过大量灰土试样的无侧限和三轴试验,对灰土强度的影响因素和水稳定性做了一定的研究,得到了灰土强度与龄期、配灰比、击实功之间的一些规律。
Illuminated by the methods in which chen huifa used to study on the constitutive relationship of concrete , the author raised the failure model of cementation shaft when studying on the constitutive relationship of lime - loess . the result of the calculation and analysis is valuable to designer and builder 在灰土的本构关系方面,作者受到陈惠发等研究混凝土本构关系时采用有关方法的启发,提出了灰土的胶结杆脆断模型。计算和分析结果可供设计施工人员参考。
There are many methods of foundation consolidation for civil engineering , such as soil exchange method , prepress method , dynamic consolidation method , vibrancy rushing method , soil and podsol dense pile method , sand pile , cement - coal - powder and gravel pile method , deep mixing method , high - pressure eject masonry , etc . the dynamic consolidation and deep mixing method ( dmm ) are very common in project construction 目前国内外地基处理的方法很多,主要的地基处理方法包括:换填法、预压法、强夯法、振冲法、土和灰土挤密桩法、砂桩法、水泥粉煤灰碎石桩法、深层搅拌法以及高压喷射注浆法等。其中强夯法和深层搅拌法是工程建设中较常用的加固方法。
We can use both calcium carbide dust and calcium carbide dust - flyash to stabilize fine - soil . as well as being used in subbase of high grade road , calcium carbide dust stabilization and calcium carbide dust - flyash stabilization can be used in basecourse of low grade road . so we can deduce that calcium carbide dust - flyash - gravel stabilization can be used in basecourse of high grade road 我们可以利用电石灰来稳定细粒土,利用电石灰和粉煤灰来稳定细粒土。通过数据分析,这种电石灰稳定土和电石灰二灰土完全可以刚于高等级公路的高级路面的底基层,也可以用于低等级公路的路面基层,同时推断,用电石灰和粉煤灰来稳定的级配碎石,可用于高等级公路的路面基层。
He claims to throw nine pitches - - when asked before the game which pitches torre might be most interested in seeing , the manager deadpanned , " strikes " - - and dusted off a forkball for his effort against the mariners , a pitch he threw sparingly in the minor leagues but leaned on a great deal in high school 他主张投九个好球,当赛前被问到老爹也许有兴趣看到的投球,老爹面无表情,且面对水手时将叉擦球上的灰土擦乾净,这在小联盟时候他很少投,但是他在高中的时候却很倚重指叉球。
In order to establish the non - destructive detecting standard , transverse wave speed is chose as the non - destructive detecting parameter , which strongly correlated with the compressive strength basing on lots of room experiments , and finds the relation between transverse wave speed of cement - soil and its contributory factors . the forecast model of the non - destructive detecting parameter is established by neutral - network toolbox of the matlab . by this model , transverse wave speed and compressive strength are got by putting the soil style , cement - soil ratio , water - cement ratio , maintain condition and the time 由于水泥土的力学性能通常用抗压强度来衡量,因此,我们通过大量的水泥土室内试验建立了剪切波速与抗压强度以及影响因素之间的对应关系,并利用matlab神经网络工具箱建立了防渗墙施工质量无损检测指标的预测模型,即通过输入土类、灰土比、水灰比、养护条件及龄期获得相应的剪切波速和抗压强度。
Calcium carbide dust pollutes environment seriously and in addition , the question of storage restricted the development of the corporation . to settle the question about calcium carbide dust is imperative under the situations . the text expatiated the application of calcium carbide ash in highway building . the article includes five aspects : 1 . application of lime soil 本文主要阐述电石灰在公路工程中的应用,为说明问题,全文共分五个部分,即一、石灰土在公路工程中的应用;二、二灰土的应用;三、石灰粉煤灰稳定级配碎石;四、电石灰应用;五、对沧州地区柔性路面结构组合的建议。
