垂直节理

通过黄土非饱和渗流试验研究，对黄土垂直节理、大孔隙的实地观察和用土壤水动力学理论分析，证明黄土介质中的垂直节理、大孔隙在不同含水量下对水分入渗所起的作用。

This study , through experiment on unsaturated seepage , field observation on vertical joint and large pore space in loess and theoretical explanation in terms of hydrodynamics suggests that vertical joint and large pore space may act differently on permeability during water seepage under different water content .

遗传性关节发育不良此处石英砂岩垂直节理十分发育，与岩层层面正交。

Vertical bedding joints in quartz sandstone are well developed , perpendicular to the plane of the formation .

黄土高边坡的节理按成因可分为垂直节理、风化节理、滑塌节理、湿陷节理四类；

The joints of high slope of loess can be divided into vertical joints , weathered joints , slump joints and collapsibility joints ;

岩层产状平缓，垂直节理发育，第四纪冰期的缺失都为岩柱群地貌的形成提供了有利的条件。

Rock occurrence flat , vertical joints of the development , the missing Quaternary glacial were good for the formation of this landform .

其形成基础是厚层、坚硬、产状平缓、垂直节理发育的石英砂岩夹薄层粘土岩。

Its formation basis is the clay rock which is thick layer , hard , the shape is gentle , vertical development and quartz .

对于沿着垂直节理方向施加冲量的块煤产生的断裂面平整，破碎的块数较少；

The fracture surface of lump coal when the impulse is exerted on the vertical bedding is smooth and the broken block number is fewer ;

由于马兰黄土结构特殊，垂直节理发育。采用室内土柱实验会破坏马兰黄土的结构，影响渗透系数，仿真模拟性较差。

Because the structure of Malan Loess is very special , it developed advanced vertically , using soil pillar in lab would break the natural structure of Malan Loess and influence the filter coefficient .

对干旱地区黄土，由于降水量小、土壤含水量少，垂直节理、大孔隙在水分入渗过程中实际起降低渗透性的作用，即阻水作用。

For the loess in arid area , due to small precipitation and water content in soil , the joint and large pore space , in substance , play a role of reducing the permeability , that is the role of water-resisting .

他们的形成是与花岗岩的坚硬岩性，具有水平节理和垂直节理、新近纪的构造抬升、第四纪气候的变化密切相关，其中花岗岩的块状结构体和层状结构体和第四纪冰缘作用起主导作用。

Their formation is closely related to the firm rock character , horizontal and vertical joints , Neogene tectonic uplift and Quaternary climatic change . Among these , massive and layered structures of granite and Quaternary periglacial action play a dominant role .

受构造应力作用，垂直层面的X节理、平行岸坡的陡倾卸荷裂隙和层理组合发育，形成了具有类似槽型状的特殊滑坡边界，三维空间效应明显。

It is created by tectonic stress , the vertical dimension of the " X " joints , parallel to the steep banks dump unloading cracks and bedding portfolio development , formed a similar special-shaped slide groove borders . It has clear three-dimensional effect .
