Based on the basic model of ideal elastic-plastic p-y curve method, this paper derives the differential equations of the laterally loaded single pile in undrained clay sloped ground by introducing the existing related reduction variable function, and the corresponding finite difference method for the pile deflection and internal force is obtained.
(1) A nonlinear analysis method for laterally loaded long-flexible pile in undrained clay sloped ground is established.
In another study, Hedge, McCrobie, Land, Morimoto, and Rodriguez (1995) investigated negatively sloped keyboards in a corporate office in Phoenix, Arizona.
In a third study of negatively sloped keyboards, Albin (1997) measured the wrist extension of users typing on a conventional keyboard supported by a platform sloped at three angles: horizontal, positive, and negative.
In summary, it appears from the literature that negatively sloped computer keyboards do reduce wrist extension.
Results from this laboratory study can form the basis for a field study of computer users who type on sloped keyboards to ascertain whether sloping a keyboard negatively reduces wrist extension angl e in actual work situations.
As shown in Figure 1, a fixture for an IBM-compatible, conventional QWERTY keyboard was built so the keyboard could be sloped at precise, predetermined positive and negative angles.
