胶结

The direct result of interaction of liquid and reservoir rock is the precipitation of calcite and dolomite, which will occupy some pore space of the source rocks and create cements, then the calcareous incrustation will be formed.

流体与储集岩作用的直接结果是方解石和白云石沉淀到储集岩中，它们将占有原岩的部分孔隙空间，形成胶结物，进而形成钙质结壳。

Therefore, we suggest that highly desires of cementing quality be needed to tertiary infilling well.

因此，对三次加密井固井质量提出了更高的要求：必须所有小层封固良好，射孔井段隔层水泥胶结指数≥0.8。

But the strata with high ground water level are composed of alluvium clays、 silty clay、 gravels and crushed stone soils in Chengdu;And the shield will drive in the interzone with complicated geologic environment, especially in the strata contained more than 50 percent of grav

而成都地铁工程将主要穿越由冲积粘性土、粉土、砂砾和碎石类土组成的覆盖层，地下水位高，盾构将通过大量地质条件和环境条件均极为复杂的区间，特别是地层中还夹杂有大漂石、胶结砾石层、粉细砂透镜体，隧道围岩中直径大于5cm的砾石含量一般都在50%以上，最大的漂石直径达1m左右，且地面多为建筑物密集的繁华地区，施工难度大，国内尚无先例，在国外也无完全成熟的经验。

The results show that the sandstone reservoirs with high porosity and permeability are mainly composed of coarse-grained lithic quartz sandstone and quartz sandstone with relatively well-preserved primary intergranular pores, relatively large median radius and average pore throat radius, and relatively low displacement pressure.

结果表明：组成高孔、渗储层的砂岩类型主要是粗粒的岩屑石英砂岩和石英砂岩，其较多地保存了原生粒间孔，具有较高的中值半径和平均喉道半径以及较低的排驱压力；高能环境下有利的沉积微相和成岩早期包壳状胶结物对原生粒间孔隙的保护作用是形成高孔、渗储层的基础条件。

The contribution ratio of matric suction on the frictional resistance increases with an increase of the net normal stresses.

黏土岩在剪切过程中存在着剪胀现象，由于原生裂隙、软弱面和铁锰氧化物胶结的影响，豁土岩的剪胀性随基质吸力而增加的规律性不明显。

The diageneses include compaction, cementation, metasomatism and dissolution, etc.

成岩作用包括压实作用、胶结作用、交代作用、溶解作用等。

It bonds rubber coverings, homogeneous and heterogeneous PVC coverings, linoleum and cork coverings, textile and needle punch coverings, particularly for use on nonabsorbent and preshaped substrates, such as steps.

可以胶结橡胶铺地、均匀异构的聚氯乙烯铺地、油布和软木铺地、纺织品，以及针冲压铺地，尤其是用于不吸水的预成形基板，如台阶。

It is revealed by the saturated single liquid seepage experiment performed by FDES-641 triaxial system that the movement of low speed seepage in low permeability media departs from the law of Darcy, meanwhile the curve of seepage flow would not pass through the origin of coordinates.

本论文作为国家自然科学基金资助项目"低渗透弱胶结岩石非线性渗流机理研究"的一个组成部分，通过对低渗透岩石系列渗流实验结果进行深入研讨并结合数值分析的方法，对该课题开展了研究。

Based on investigation of the moraine and outwash deposits in above regions, the authors find that they are very complicated Quaternary deposits with special composition, structure and properties. Their engineering properties are mainly related with the composition of the gravel and the filled material.

通过对上述地区大量冰碛物和冰水沉积物的现场调查发现，冰碛物和冰水沉积物是一类成分、结构和性质都十分复杂的第四纪堆积物，其工程性质主要与母岩成分和充填胶结物的矿物成分密切相关。

E. g. the moraine and outwash deposits distributed in limestone areas can turn into rocks, named moraine rock or outwash rock, caused by calcite cementation, which has a uniaxial strength from 10.94MPa to 14.22MPa.

发育在石灰岩地区的冰碛物和冰水沉积物因钙质的次生胶结，而成为单轴抗压强度达10.94~14.22MPa的岩石，作者称其为"冰碛砾岩"。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
