在重型击实或碾压后，砾质土的工程性质主要受粗粒含量的不同而变化。

After heavy tamping or compaction by rolling , the engineering properties of gravelly soil change with different coarse grained contents .

对非饱和砾质土心墙料做一组等应力比和等应力增量比为常数的试验，发现邓肯-张模型基本能反映该应力路径下的应力应变关系。

Analyzing the test results , the Duncan-Chang model can basically reflect the coarse grained soil 's stress-strain relationship under the stress path of dam .

试验结果表明，击实砾质土抗拉强度随着干密度的增加而增加，增加幅度显著；

The results of the tests indicate that the tensile strength of the soil increases with the dry density increasing , and the increment is obvious .

在所试验的含水率、密度和前期固结压力范围内，试验得到的砾质土抗拉强度为20～80kPa。

Within the investigated ranges of water content , dry density and preconsolidation pressure , the tensile strengths of the soils vary from 20 to 80 kPa .

其次，对3种不同粗料含量的非饱和砾质土心墙料做不同含水量下的不固结不排水试验，研究粗料含量和含水量对砾质土的力学性质的影响。

Second , a series of UU tests for three kinds of unsaturated gravelly soils with different coarse material content ( P5 ) and different water content are performed .

砾石土/砾质土的水分含量与砾石含量、砾石的来源、大小、孔隙度以及砾石在土壤中存在的位置有关；

The water contents in soils containing rock fragments are associated with origin , content , size , and porosity of rock fragments and its position in the soil profile .

试验研究还认为，只要解决好渗透稳定问题，做好反滤保护，砾质土作心墙防渗体是可行的。

In this article the conclusion was got from some experiments and researches that the crux of the matter is to solve the seepage stability of the soil and it is possible that gravelly soil is made into impervious core with the protection of filter .
