It is shown that the shape of curves is related to the rock weathering of bearing strata and rock-socketed depth .

岩石风化程度的划分及工程特性研究，对于工程基础面高程的选择以及工程环境或工程材料的利用具有重要意义。

Classification of weathering intensity of rocks and research on their engineering features are important to the selection of foundation elevation and the utilization of engineering environment or materials .

本文介绍用浅层折射波法、波速测试、电测井、放射性测井、旁压试验及点荷载试验等方法综合评价岩石风化程度的工程实例。

This paper introduces a comprehensive evaluation for the degree of weathering of rocks by shallow seismic refraction , wave velocity test , electric logging , radioactive logging , pressuremeter test and paint load test .

就矿物成分特征而言，随着玄武岩风化程度的加剧，长石含量逐渐减少。因此长石的次生蚀变率可以作为玄武岩岩石风化程度判识标准之一。

In terms of the mineral characteristics , it is found that feldspar content decreased with increasing weathering intensity . Therefore , secondary alteration of feldspar can be taken as a sign of the weathering intensity .

应用模糊综合评判对岩石的风化程度进行判别。

This article uses vague comprehensive assessment to judge the weathering degree of rock .

研究发现，湖泊的自然地理条件、流域岩石土壤风化程度、湖泊生态系统类型及生物量、再悬浮及受人为扰动程度等均是影响湖泊沉积物中硅地球化学特征的重要因素。

The results showed that some important factors including the natural geography condition , the degree of rock weathering and erosion , the type of lacustrine ecosystems and biomass , re-suspension and human disturbance all affected the geochemical characteristics of silicon in lake sediments .

在攀登前，应识别岩石的质量和风化程度。

Before climb , should identify the quantity moderate breezes of the rock to turn the degree .

另外，岩石材料由于其风化程度不同或所含成分及含量不同，其疲劳损伤演化进程也都不相同。

Furthermore , the evolutionary processes for the fatigue damage of rock and concrete are different due to the differences of weathering degree , components and their contents .

给出的定量指标很好地反映了风化岩石质量，且与反映岩石风化程度的一些物理力学指标存在良好相关性。

The quantitative indexes given can clearly reveal the change of the quality of weathered rocks , and agree well with the indexes of the physical and mechanical properties of rocks .

由于自然界岩石的风化作用是一个连续的阶段过程，不同风化程度的岩石其结构和矿物组成也不相同，因此岩石的风化程度可以作为判定其是否为松散堆积物的依据。

Weathering processes of rocks in the nature is a continuous procedure . The rocks have different structures and mineral he mineral components in different phases . The weathering phase of rock could be used to determine whether it is loose deposit or not .
