In the light of its special property being not easy to gain strength, through mechanics researches on different methods to stabilize this kind of low _ liquid _ limit silty soil as subbase material, evaluated both technically and economically, we have got a cement lime stabilization plan to meet the index requirements for non _ side _ limit strength of compression of subbase of class2 road stipulated in the specification ; by means of improving the workmanship, thickening the loose layer of soil, adding soil on covering weave fabric before compaction, such problems can be solved as very poor compaction, loose surface during compaction, roughness and unevenness, coats of layer and shear damages
本文針對黃河沖積而成的低液限粉土其粘粒含量極低、土的不均勻系數很小、膠體活性差的工程特性，通過採用不同方法穩定該類土作底基層材料的力學性能研究，從技術、經濟角度綜合評價，得到滿足規范抗壓強度指標要求的水泥石灰穩定方案。通過對原材料、試驗配合比設計、施工、等方面進行優化，從而顯著減輕了基層的早期及長期縮裂程度，從而提高了路面的耐久性。 -
The unconfined compressive strength, shearing strength and permeabi lity of stabilized soils were tested in laboratory, the strength of contaminated composite soils sampled with different ph and soaped in corresponding ph were compared. the results from experiments indicate that there exists a certain relationship between the soft soil properties and the unconfined compressive of grouted soil. with the increase of water content, porosity ratio, degree of porosity, plasticity limit, liquid limit and liquid index, the compressive strength of cement - sodium silicate - stabilized soil decreases, while increases as the bulk weight and compressibility modulus
通過對水泥?水玻璃加固土的無側限抗壓強度試驗，以及用不同酸堿性水製成與養護的固結土所進行強度對比試驗，得出軟土的物理力學性質指標與加固土的抗壓強度之間存在一定的相關關系，即隨著含水量、孔隙比、孔隙度、液塑限及液性指數的增加，水泥?水玻璃加固土的抗壓強度相應地降低；而隨著原狀土的容重、壓縮模量的增加，水泥土的抗壓強度也隨之增加。 -
