泥灰岩

A lot of brachiopod and mollusk fossils,including 12 species of 8 genera of brachiopod,14 species of 8 genera of bivalve and 5 species of 4 genera of gasteropod,are collected from the marl and mudstone situated on the bottom of Benxi Formation in Liujiang basin.The mollusk fossils are directly preserved in the upper part or facies change bed of brachiopod fossil bed.Up to now, the materials is firstly reported,especially the mollusk.

Hunji rock as well as the concept and system about mixing deposits were introduced into the classification of sediment type and lithofacies and thus provide proofs for scientific definition of marl.

在进行了详细的岩心、薄片观察和各种分析化验资料的综合分析基础上，认识到研究区岩石为混积岩类，将混积岩、混合沉积的概念和体系引入沉积物类型和岩相的划分中，为泥灰岩的科学定名提供了依据。

At middle and low temperature, there is more hydrogen, more nitrogen, higher dry coefficient and ratio of ethane content to propane's in marlite than in shaly limestone.

在中、低温度段，泥灰岩所产气体的C1/ΣC+1、C2/C3值和所产氢气、氮气的量高于纯灰岩。

The results of laboratory reconstituted permeability tests show that the permeability coefficient of remolded marlite samples is greater than that of the reconstituted clay rock when their dry densities are the same with natural water content.

室内重塑渗透试验结果表明：天然含水率下相同干密度的重塑泥灰岩的渗透系数大于黏土岩，其渗透系数随干密度的增大而减小的速率小于黏土岩，且测得重塑膨胀岩样渗透系数均小于场地的原位渗透系数。

For Goupitan Hydropwer Station on Wujiang River,over 1 200 anti-uplift anchor pile s are arranged in the water cushion pool to anchor the non-uniform soft rock strata composed of shale,clay rock,silty clay rock,thin layer of marlite and less medium-fine calcareous sandstones etc.

乌江构皮滩水电站水垫塘部位布置了1200多根抗浮锚桩，对页岩、粘土岩、粉砂质粘土岩，及夹薄层泥灰岩和少量中细粒钙质砂岩等不均质软岩层软岩进行锚固，原设计锚桩的间距为2.2m，为了优化设计，缩短工期，在施工前进行了4根锚桩原位抗拔试验，根据锚桩在抗拔过程中周边一定范围内岩体变形沿径向的分布规律，及破坏时裂隙的扩展形态和范围，确定了锚桩的间距，在此基础上提出了锚桩间距的优化方案，并应用于工程施工。
