泥崩

Red mudstone is a special rock. It has some special characteristics, such as low compression strength, softening, disintegration, dilatability and sensitive to the reclamation compaction degree when meeting with water.

红层泥岩是一种特殊岩土，具有抗压强度低、易风化、遇水易软化、崩解、膨胀、填筑密实度对含水量很敏感等特点。

Bacterial strains were isolated from humus mud by employing the dilution methods. Seven cellulose-degradation Strains marked as B-37, B-35,B-31, B-25, B-17, Z-a, and Z-b were selected according to the hyaloid rings on the medium of carboxymethylcellulose sodium Congo red and their efficacy of decomposing filter paper. Z-b had the strongest ability in decomposing filter paper among the seven strains and 16S rDNA analyzed indecated that it was Stenotroplaomnonas maltophilia owning to 99.8% homology. Comparing clony size of the seven strains in media with different carbohydrates and inorganic salt, we found that the potato extract and inorganic salt which contained CaCl2 0.20, MgSO4 1.25, NaCl5.00,(NH4) SO4 1.30, KH2 PO4 1.35, FeSO47H2O 0.015, Na-EDTA 0.02 were suitable for the bacteria growth.

用稀释法从腐殖泥中分离菌株，根据它们在梭甲基纤维素钠-刚果红培养基上的透明圈直径及对滤纸的崩解能力，获得7株纤维素分解细菌（编号：B-37、B-35、B-31、B-25、B-17、Z-a和Z-b），其中菌株Z-b的纤维素崩解能力最强，分子鉴定结果表明它与Stenotrophomonas maltophilia的16S rDNA序列有99.8%的同源性，初步确定为嗜麦芽窄食单胞菌。

Utilizing the scanning electron microscope, X ray diffractometer, type 9310 microporosity analyzer, the microstructure and chemical composition of mudston, and its macro variation of physical and mechanical character are measured and analysed, the mechanism of mudstone degradation and softening in water is systematically studied in this paper.

以扫描电子显微镜、X射线衍射仪、93 10型微孔结构分析仪等先进的设备为测试手段，从泥岩的微观结构及物质组成等方面入手进行研究，结合泥岩遇水后宏观物理力学性质的变化规律，全面阐述了泥岩遇水的崩解软化机

泥岩遇水崩解软化机理的研究。

The physical and water-physical parameter of the mudstone is tested.

由不同含水状态下的室内崩解试验发现，紫红色泥岩具有较强的崩解特性，且与岩石的物理状态密切相关，试验得到岩块的力学性质指标和变形特征。

In fact,disintegration is a process of soft rock's dehydration,absorbing water and expansion.

崩解、泥化实际上是岩体失水—吸水—膨胀的过程，水在这个过程中起着关键性的作用。

In fact, disintegration is a process of soft rock＇s dehydration, absorbing water and expansion.

软岩的崩解、泥化往往给工程带来困难和损失。

This mudstone formation is deposited from the late Tertiary to the early Quaternary. Due to the shorter digenetic period, it has some unfavorable properties such as lower strength, swelling and slaking behaviors, lower resistance of weathering, etc.

泥岩形成於第三纪的末期及第四纪前期，成岩时间较短，强度较低，遇水后易产生回胀、崩解的现象，抵抗外在环境的能力较差，特别是水的影响。

几种典型软岩岩组的崩解特性后，获知该类软岩极易吸水，遇水后发生泥化、软化和崩解。

Clay is the main mineral of interbedded mudstone of rock salt. The illites/smectite mixed-layer mineral is the main formation of clay in interbedded mudstone. Granule particle is main in interbedded mudstone. Interbedded mudstone slakes by stratification bedding and little expansion.

盐岩层间泥岩夹层的主要矿物为黏土矿物，黏土矿物的主要存在形式为伊利石／蒙脱石混成矿物；泥岩夹层主要为细粒颗粒；泥岩夹层沿层理面崩解，层状开裂软化，具有微膨胀性。

Plunder melds and run with this jewel!

My dream is to be a crazy growing tree and extend at the edge between the city and the forest.

此刻，也许正是在通往天国的路上，我体验着这白色的晕旋。
