Blood pressure is one of the crucial parameters that can reflect the state of cardiovascular system, the heart capacity of pumping blood, heart rate, peripheral resistance, arterial stiffness and physical condition of blood are all the important parameters, and it is significant for the diagnosis and prognosis for cardio.

In order to proof bearing capacity of single pile and find out friction resistance around pile and pile base resistance,the load transfer and resistance analysis test of end-bearing pile are taken by using the load and strain test of drilling hole perfusion end-bearing pile and the cyclic loading method.
