The water resources severity of the xingtai city is short of , but , tiny salt water in eastern plain is extensive , store more abundant , and cover up deeply and more shallow , easy to mine 摘要邢台市的水资源严重匮乏，但是，东部平原微咸水分布广泛，储存较为丰富，且埋深较浅，便于开采。
And the effects of liquefaction sand soil on surface ground motion are investigated for considering the thickness 、 depth 、 width of the liquefied sand layer and the input earthquake wave 主要分析了饱和液化层厚度、饱和液化层埋深、土性参数和输入地震波等因素对地面加速度反应谱的影响。
In this research , model of groundwater level distribution using remote sensing ( arglutm ) was established using landsat - 7 etm + image , by dint of practical work and field examination data 二是应用visualbasic将rs与gis结合起来，提出一种可以有效提高rs数据制作地下水埋深专题图精度的方法。
There is still an extensive arable land left unused due to the acute conflict of supply and demand resulting from the great shortage and low efficiency of water resources 灌区尚有连片大面积的宜开垦地，但是水资源极为紧缺且利用率低下，供需水矛盾十分突出，灌区地下水埋深较浅，土壤盐碱化严重。
Under the ground lever there is an upper sand layer of river at 10 . 5m and a lower sand layer of river at 12m . some fossils , stone artifacts or ashes were found in the layers while digging bases for some buildings 施工开挖中发现，在埋深大约10 . 5m和12m处分别有2层河流砂层，含化石石器灰烬等物。
Based on the study of oil and gas origin , source rock maturation and hydrocarbons expulsion history as well as structural development history , oil and gas reservoirs " formation timing is studied 陆梁地区的天然气大致可分为两类，埋深小于1500n的生物气或生物气hb温热解气和埋深大于1500 。的油型气。
The vibration propagation is prodigious influenced by geological condition and the depth of tunnel . at last , linear method is carried to study the attenuation empirical formal of vl 地质条件、隧道埋深对振动波的传播影响较大,在离开隧道轴线一定距离存在一个振动放大区,在此区域内地面振动强度有所增大。
It was showed that the fractal characteristics of magnetic anomaly reflects the variations of physical factors of subsurface magnetic source , and is affected by the burying depth and extending depth of the source 分析认为磁异常具有分形结构，分维值与浅源磁化率分布有关，并受其埋深、延深等几何因素的影响。
There are few great depth , high external waterpressure and high geostress tunnels engineering and few researches on this up to present . thus , there will be many challenges in construction of the tunnels 如此大埋深、高外水压力、高地应力下的隧洞工程建设目前还很少有同类工程可资借鉴，这方面的研究也不多见。
The jiangkou hydropower station adopt double curve dam and underground powerhouse . major structures for the underground powerhouse were built under the ground , the whole cavern mass are quite complicate 该水电站采用双曲拱坝、地下厂房设计方案，厂房埋深约120m ，水电站的主要建筑物均修建于地下，整个地下洞室群错综复杂。
