建筑桩基桩周土层相同，下列（）项桩端土层情况下的填土引起的负摩阻力最大。（）

（）是指采用锤冲击桩顶，使桩周土产生塑性变形，实测桩顶附近所受力和速度随时间变化的规律，通过应力波理论分析得到桩土体系的有关参数。

Every deliberate act of wrongdoing by the master or any of the crew against the ship or cargo，without the authorization or privity of the Shipowner or his agent，is（）.

（）, or drum is used for hauling in or letting out the wires or ropes which will fasten the ship to the shore.

逻辑运算符（AND、NOT、OR）的运算顺序是AND→OR→NOT。

当桩周产生负摩阻力时，下述（）不正确。

在黏土中连续沉桩时，由于土中水的作用，会使桩周摩阻力（ ）。

沉入土中的桩，将使桩周附近（ ）倍桩径范围内的土受到很大的重塑作用，因此在黏土中沉桩时，当桩距较小时，更应注意沉桩顺序。

逻辑运算符（AND、NOT、OR）的运算顺序是AND→OR→NOT。
