The value of frictional force of soil to pile body and resistance to pile toe has a close relation with the penetration depth and relative rigidity of soil layer at pile body and pile toe.
支承桩的桩身摩擦力和桩尖阻力的大小与入土深度及桩身、桩尖处土层的相对刚度密切相关。
Open constructions, which offer little resistance to soil penetration, may require more maintenance than tight constructions, which shed dirt.
稀疏的织物结构几乎对灰尘没有阻挡作用，在维护方面要比紧密织物结构复杂得多。
The cone penetration test(CPT) can't be used in harder soil such as loess or in deeper soil because of the higher cone resistance and the limited capacity of the equipment of CPT.
由于现有静力触探机械设备提供的动力有限，使得静力触探技术无法应用于较硬土层或较深土层中（应力较高）。
